Food Chain and Food Web
A food chain shows how energy flows between organisms as one organism eats another. A food web shows multiple interconnected food chains within an ecosystem. Producers like plants use sunlight to make their own food, while consumers eat other organisms and decomposers break down dead organisms. Energy is lost at each transfer between trophic levels according to the 10% law.

The document discusses food chains, food webs, and food pyramids. It explains that in a food chain, energy passes from producers to consumers as herbivores eat plants, carnivores eat herbivores, and omnivores eat plants and other animals. A food web shows the interconnected food chains in an ecosystem. A food pyramid depicts the transfer of biomass and energy between trophic levels, with higher levels containing less biomass since most energy is lost as it moves up the chain.Food chains
A food chain describes how energy passes from one organism to another. Producers like plants get energy from the sun, consumers eat producers or other consumers, and decomposers break down waste. A food chain shows a single path of energy transfer, while a more complex food web links multiple food chains together as predators can have multiple prey.
Food web
The document defines key terms related to food chains and food webs, including producers, consumers, decomposers, trophic levels, and ecological pyramids. It explains that plants are producers that make their own food, while consumers eat other organisms and are divided into primary, secondary, tertiary, and sometimes quaternary levels. Decomposers break down waste and release nutrients. Food webs show interconnected food chains and the flow of energy and matter through an ecosystem.
Biology ecology
The document discusses different levels of organization in ecology, from cells to the biosphere. It explains key ecological concepts like producers, consumers, herbivores, carnivores, omnivores, decomposers, food chains, food webs, and energy flow through ecosystems. Primary productivity is defined as the rate at which producers create new organic material. Major biogeochemical cycles like the water, carbon, and nitrogen cycles are also summarized.
Energy Flow In An Ecosystem
Here are the key points about how energy flows through ecosystems:
- Energy from the sun is captured by producers (plants) through photosynthesis and stored as chemical energy in glucose.
- Primary consumers (herbivores) obtain energy by eating producers. Secondary consumers (carnivores) obtain energy by eating primary consumers. Tertiary consumers obtain energy by eating secondary consumers.
- Most energy is lost at each transfer between trophic levels, so the amount of available energy decreases moving up the food chain.
- Scavengers and decomposers (bacteria, fungi) break down dead organisms, recycling nutrients back into the soil/environment where producers can use them again.
- Nutrient cycling
Ecosystems: Food chain
Producers such as trees feed on sunlight and water and provide nutrients to other living things. Consumers include animals that are heterotrophic and eat other organisms to survive. There are three types of consumers: herbivores that eat producers, carnivores that eat other consumers as hunters or scavengers, and omnivores that eat producers, consumers, and sometimes decomposers. Decomposers such as fungi and bacteria decompose remains of other organisms and release nutrients into the soil. A food chain shows the relationships between producers, consumers, and decomposers.

FOOD CHAIN & FOOD WEB
This document discusses food chains and food webs. It defines a food chain as the transfer of energy from one organism to another as one organism eats another. There are two main types of food chains: grazing and detritus. A food chain contains producers, consumers, and decomposers. Multiple interconnected food chains form a food web. Ecological pyramids illustrate the biomass, numbers, or energy at each trophic level and typically show decreasing amounts at higher levels.
Ecosystem Relationships
The document discusses ecosystems and food webs. It defines producers as organisms that make their own food, mostly plants. Consumers must find their own food and include all animals. Decomposers like worms and fungi break down dead and decaying matter. Herbivores eat only plants, carnivores eat only meat, and omnivores eat both plants and meat. A food chain shows the transfer of energy from producers to consumers, with the sun as the original energy source. A food web connects overlapping food chains and shows how all animals in a community obtain food. An energy pyramid displays the decreasing amount of energy at higher levels of the food web.
Food chain group 3-9 f
A food chain shows how organisms obtain energy and nutrients by consuming other organisms. Food chains begin with autotrophs, like plants, that produce their own food. Herbivores then eat the plants, and carnivores eat the herbivores or other carnivores. This continues with increasing trophic levels until reaching top predators with no natural predators. At each level some energy is lost, with decreasing amounts of energy being passed to higher levels.
Food chain,food web and ecological pyramids
The document discusses food chains and food webs within an ecosystem. It defines a food chain as the transfer of energy from producers, like plants, through consumers at different trophic levels, and explains the key levels as producers, primary consumers, secondary consumers, and decomposers. Food webs are described as interconnected food chains that form a network of feeding relationships between species. Ecological pyramids illustrate the structure of ecosystems by depicting the numbers, biomass, or productivity at each trophic level, with producers at the base and top predators at the apex. Disturbances like bioaccumulation and biomagnification of chemicals can disrupt ecosystem balance.
Food Chains and Food Webs (PowerPoint)
This document discusses food chains and food webs. It explains that a food chain begins with an energy source like a producer and is made up of different trophic levels including producers, primary consumers, secondary consumers, and tertiary consumers. Producers make their own food, primary consumers eat plants, secondary consumers eat herbivores, and tertiary consumers eat other carnivores.
Food chain and food web
This document discusses food chains and food webs. It describes how food chains involve the transfer of energy from producers like plants to consumers in a linear progression. Food webs are more complex networks of interconnected food chains that provide stability. They connect organisms and maintain ecosystems by balancing energy transfer between trophic levels and sustaining biodiversity.
The Food Web PowerPoint
This presentation is a PowerPoint on the Food Web I completed in Geology. This goes into great detail about consumers, producers, and decomposers.
Food chain
1) Food chains and webs describe the feeding relationships between organisms in an ecosystem, with producers like plants at the bottom and various consumers at higher trophic levels.
2) Biomass pyramids show that the amount of biomass decreases at each higher trophic level due to energy losses as energy moves through the food chain.
3) Certain harmful substances can accumulate and concentrate in organisms at higher trophic levels through biological magnification as they are not easily broken down or excreted.

Unit 3 lesson 1 food chains
This document defines key terms related to ecosystems, including producers, consumers, decomposers, food chains, and food webs. It provides examples of each trophic level and discusses how energy flows through ecosystems. Producers, like plants, capture energy from the sun that is then consumed by primary, secondary, and tertiary consumers. Decomposers, such as bacteria and fungi, break down dead organisms and waste. While nutrients cycle through the ecosystem, most energy is lost as heat at each trophic level, with only 10-15% transferred to the next level.
Trophic levels
Primary producers use energy from the sun or chemicals to produce organic molecules. Consumers rely on other organisms for energy and nutrients. There are different types of consumers including herbivores, carnivores, omnivores, scavengers, decomposers, and detritivores. Food chains show the transfer of energy between organisms through eating, while food webs show complex feeding relationships in an ecosystem. Trophic levels refer to the steps in a food chain, with primary producers at the base and increasing consumer levels above. Only about 10% of available energy is transferred between trophic levels.
2.1 Energy Flow In Ecosystems
Organisms in an ecosystem play one of three roles: producer, consumer, or decomposer. Producers such as plants make their own food, consumers such as herbivores, carnivores, omnivores, and scavengers obtain energy by eating other organisms or dead matter, and decomposers such as bacteria and fungi break down waste and dead organisms. Energy flows through food chains and food webs with producers containing the most energy and higher levels containing less energy. Food webs better represent ecosystems as most organisms are involved in multiple overlapping food chains.
2 food chains in ecosystem
This document discusses food chains and food webs. It defines key terms like producers, consumers, decomposers, herbivores, carnivores and omnivores. Producers like plants and algae are at the bottom of food chains, using photosynthesis to produce energy from the sun. Consumers eat other organisms to obtain energy and nutrients, and decomposers break down dead organisms, recycling nutrients. Food chains interconnect to form complex food webs in ecosystems. Energy is lost at each trophic level, as shown in energy pyramids, with fewer organisms at higher levels requiring more resources from below. Maintaining healthy food chains is important for sustaining all life.
Habitats and foodchains
An ecosystem refers to all the plants and animals that live together in an environment and interact. Different ecosystems can exist close together and some animals belong to multiple ecosystems. All living things are adapted to their environment and habitats in ways that help them survive, such as how seals are adapted to aquatic life. Food chains show what organisms eat other organisms or plants, and start with producers like plants. When one part of a food chain is disrupted, it can negatively impact other parts of the ecosystem. Human activities like habitat destruction and pollution are common reasons why some animal populations become endangered or extinct.
Marine food chain
This document summarizes marine food chains and webs. It defines a food chain as the linear path of energy transfer between organisms, with producers, consumers, and decomposers. Food webs are more complex diagrams showing all feeding relationships. Phytoplankton are primary producers that are eaten by copepods, which are eaten by herring. Ocean food webs vary in efficiency, trophic levels, and primary productivity. Primary productivity is due to photosynthesis, while secondary productivity is from consumer organisms.
food and web chain
This document discusses feeding relationships and food webs in ecosystems. It defines key terms like producers, consumers, decomposers, herbivores, carnivores, omnivores, and describes different types of interactions like commensalism, mutualism, and parasitism. Examples of each are provided. Food chains and food webs are explained, showing the transfer of energy from trophic level to trophic level. Energy pyramids, biomass pyramids, and pyramids of numbers are introduced to illustrate how energy and biomass decrease at higher trophic levels due to energy losses between levels. Sample questions are included for students to answer.
How Is Energy Transferred
Energy is transferred through ecosystems via food chains and food webs. Green plants, or producers, trap energy from the sun through photosynthesis and serve as the base of the food chain. Herbivores obtain energy by eating plants, and carnivores obtain energy by eating herbivores or other carnivores. Decomposers, like bacteria and fungi, break down dead organisms and waste and release nutrients back into the soil. Energy and matter are transferred and pass between trophic levels as organisms consume other organisms in an ecosystem.
Ecosystem energy flow (part 2)
The document discusses key concepts about energy flow within ecosystems, including food chains, food webs, and energy pyramids. It defines producers as organisms at the first trophic level that convert sunlight into chemical energy through photosynthesis. Consumers are organisms at higher trophic levels that get energy by eating other organisms, including herbivores, omnivores, and carnivores. Decomposers break down dead organic matter and cycle nutrients. Food chains show a single path of energy transfer, while food webs illustrate the many interconnected food chains in an ecosystem. Energy pyramids demonstrate that the amount of available energy decreases at each trophic level as heat is lost during energy transfers between organisms.
Food webs ppt
This document discusses food chains and food webs. It explains that food chains show how each living thing gets energy by consuming other organisms and always starts with a producer such as a plant. Food webs are collections of interconnected food chains within an ecosystem and show the flow of energy between organisms through arrows. An energy pyramid displays the decreasing amounts of energy available at each trophic level.
4.2 energy flow
Here is a 6 mark outline of how energy passes through ecosystems:
1. Light energy from the sun is captured by producers like plants through photosynthesis.
2. This light energy is converted to chemical energy stored in carbohydrates.
3. Primary consumers eat producers and obtain this chemical energy.
4. At each trophic level as organisms eat one another, only about 10% of the energy is transferred between trophic levels with the rest lost as heat or through feces and waste.
5. This energy loss at each level limits the length of food chains and biomass at higher trophic levels due to decreasing energy availability.
6. Heat energy produced during respiration cannot be reused by organisms and

What are food chains and food webs in an ecosystem?
This document discusses food chains and food webs. It defines producers as organisms that produce their own food, typically through photosynthesis, and consumers as organisms that eat other organisms for food. Herbivores eat plants, carnivores eat other animals, and omnivores eat both plants and animals. Decomposers break down dead organic matter. Food chains show the transfer of energy as organisms eat each other, moving through trophic levels from producers to primary, secondary, and tertiary consumers. Most ecosystems involve complex food webs rather than simple food chains, as most organisms eat more than one type of other organism.
Lecture 4 consumers
Consumers are heterotrophs that obtain energy by eating other organisms. There are three main types of consumers: herbivores, carnivores, and omnivores. Herbivores eat plants, carnivores eat other animals, and omnivores eat both plants and animals. Herbivores have digestive systems adapted to break down plant material, while carnivores are more efficient at digesting protein. Omnivores can digest carbohydrates, protein, fat, and fiber from their varied diets. Examples are given for each consumer type.

The document provides examples of producers, primary consumers, and secondary consumers, and directions for a food web activity assignment.
Unit 2 a ch 5 s1 energy flow in ecosystems
1) Energy from the sun powers photosynthesis in plants and algae, producing carbohydrates that form the base of most ecosystems' food chains.
2) Some deep sea ecosystems use chemosynthetic bacteria that derive energy from sulfur compounds rather than the sun, as the base of their food chains.
3) Energy is transferred between organisms as one eats another, but about 90% is lost as heat or waste at each transfer, making long food chains unsustainable in most ecosystems.
Activity 8 Stomach Content Analysis
Frogs were collected and their stomach contents analyzed to determine their diet. Several frogs' stomachs contained darkling beetles, while others contained corn seeds or clear fluid. Darkling beetles are primary consumers that feed on plants, placing them on the second trophic level. Food chains typically have 4-5 trophic levels because not all energy from lower levels is transferred upwards, limiting populations at higher levels. A frog's diet depends on the habitat and food sources available, and more plant matter supports larger darkling beetle populations, and subsequently more frogs.
FoodChains CSEC PowerPoint Presentation for students
This document discusses food chains and food webs. It defines key terms like producers, consumers, trophic levels, herbivores, carnivores, omnivores, decomposers, predators and prey. It provides examples of food chains from both aquatic and terrestrial environments. It explains that food chains alone do not fully represent feeding relationships in an ecosystem as they do not account for omnivores or multiple feeding sources. A food web links together multiple food chains to more accurately depict the complex trophic interactions between organisms within a community.
lessons
The document discusses the relationship between organisms and ecosystems. It explains that ecosystems have both biotic (living) and abiotic (non-living) components that shape how species have adapted. Organisms can occupy different roles in ecosystems as producers, consumers, or decomposers and transfer energy through food webs. Population dynamics depend on birth, death, immigration and emigration rates, which are influenced by both density-dependent and independent factors. This affects population growth and size over time.
Flow of energy 2013-2014
1. Energy from the sun is stored by producers like plants through photosynthesis and stored as glucose. Producers are then eaten by primary consumers like herbivores. Higher-level consumers like carnivores eat those primary consumers.
2. Food chains and food webs show the transfer of energy between organisms in an ecosystem. Food chains show a single pathway while food webs show the complex interconnected feeding relationships.
3. Energy pyramids illustrate that only about 10% of energy is transferred between trophic levels, so the amount of energy decreases at each higher level. Producers form the base and consumers occupy higher levels.
Protitts chap 8 notes
1. The document discusses several animal-like protists including Euglena, Dinoflagellates, Foraminiferans, Apicomplexa, and Ciliophora.
2. Many protists are unicellular while others form colonies, and they use a variety of methods for locomotion and obtaining nutrients including photosynthesis, feeding on other organisms, and forming symbiotic relationships.
3. The protists discussed play important ecological roles such as forming sediments, causing harmful algal blooms, and serving as parasites that impact human and animal health.

Flow of energy 2013
1. Energy from the sun is stored through photosynthesis in plants. This energy is then transferred to primary consumers like herbivores that eat the plants. Higher-level consumers that eat other animals also obtain this energy, though less is available at each level.
2. Food chains and food webs show the transfer of energy between organisms in an ecosystem, with producers at the bottom and different consumer levels above. Only about 10% of the energy is transferred between levels, which is illustrated in an energy pyramid.
Nutrition in plants New (2).pptx
This document summarizes different modes of nutrition in plants. It discusses autotrophic nutrition through photosynthesis, and heterotrophic nutrition including insectivorous, symbiotic, saprophytic and parasitic plants. It also addresses replenishing soil nutrients through practices like growing leguminous plants, crop rotation, and adding manure or fertilizer. The document concludes with some practice exercises asking students to differentiate autotrophic and heterotrophic nutrition, explain why humans can't perform photosynthesis, draw labeled diagrams of stomata, and complete a flow chart or label parts of a pitcher plant.
Animal Behaviour
[1] The document discusses various types of animal behaviors including innate behaviors, learned behaviors, and different patterns of behaviors such as feeding behavior, social behavior, predatory behavior, and reproductive behavior.
[2] It provides examples of different types of innate responses in animals like tropisms, taxes, kineses, and reflexes. Learned behaviors can develop through experiences and include habituation, imprinting, and conditioning.
[3] The document also examines various patterns of behaviors in detail including social behavior in insects like bees, parental behavior in birds and mammals, and anti-predator behaviors used by animals for protection.
Ecosystem
This document defines key terms related to ecosystems, including producers, consumers, decomposers, food webs, populations and communities. It explains that an ecosystem is made up of both biotic (living) and abiotic (non-living) components that interact, including plants, animals, soil, air and water. Producers are organisms like plants that can produce their own food, while consumers eat other organisms and decomposers break down dead organic matter.

Clothes for Different Weather
Clothes are materials that are worn to cover and protect the body. Different weather conditions call for different types of clothing. In summer, when it is hot, short clothes like t-shirts and shorts are worn. In winter, when it is cold, warmer clothes like cardigans, mittens and mufflers are necessary. During rainy weather, raincoats, boots and umbrellas are used to protect from rain and cold. Clothes are also worn for purposes like identification with uniforms, celebrations, and protection from weather.
Plant Life Cycle
The document outlines the ground rules and objectives for a virtual Class 2 science lesson on the life cycle of a plant. The lesson instructs students to mute microphones, use the chat box for communication, and not use emojis. It defines key terms like seed, germination, seedling. It lists the stages of the plant life cycle as seed, germination, seedling, and adult plant and recaps that the cycle begins with a seed and repeats with the production of new seeds.

Animal Adaptations
Plants can adapt to different environmental conditions through various means. They can be found in regions like mountains, plains, deserts, coastal areas, swamps, and aquatic regions. There are three types of aquatic plants - free-floating plants, fixed plants, and underwater plants. Plants need to adapt to their surroundings in order to survive.
Seed Germination
This document outlines the ground rules and objectives for a Class 2 science lesson on germination. The lesson defines germination as the process by which a plant grows from a seed to become a new plant identical to its mother plant. It notes that seeds have three parts - a seed coat, embryo, and cotyledon - and that the cotyledon provides food for the embryo before it can photosynthesize. The objectives are to define germination, discuss conditions required, and review related keywords.
POISONOUS LIQUIDS
This document discusses poisonous liquids. It identifies common poisonous liquids like petrol, kerosene, insecticide, Dettol, liquid soap, Harpic, and acid. These liquids are poisonous because of their chemical contents, which make them unsafe for human consumption. If someone accidentally swallows a poisonous liquid, they need to go to the hospital immediately, as the liquids can cause death.
Fruits & Seeds - It's Edible part 2
The document provides information about the differences between fruits and seeds. It outlines three key differences: fruits are generally larger than seeds, fruits and seeds have different textures and colors, and fruits come from the ovary of a plant while seeds come from the ovule. The lesson objectives are for pupils to be able to give three differences between fruits and seeds and state what each one is. Key words like texture, size, and color are also provided.
Plant Adaptations 2
This document discusses how plants adapt to different environments or habitats. It provides examples of plant adaptations for various regions including mountains, plains, deserts, coastal areas, swamps, and aquatic environments. Key adaptations include needle-like leaves and conical shapes for mountain plants, small leaves and deep roots for plains plants, fleshy stems and reduced leaves for desert plants, and breathing roots for mangrove swamp plants. The document also categorizes aquatic plants as free-floating, fixed, or underwater and provides examples such as water lilies and pondweed.
Alive and Non Alive
This document discusses the difference between living and non-living things. It provides examples of living things like humans, animals and plants which can move, breathe and grow. Non-living things like buckets and stones cannot move, breathe or grow. The document encourages grouping pictures of objects as either living or non-living.
Plant Adaptation
This document discusses plant adaptations and habitats. It defines adaptation as changes that help plants survive when their environment changes. It lists several plant habitats including grasslands, rainforests, deserts, and aquatic environments. For each habitat, it provides examples of plant species found there and their adaptive features, such as broad leaves and tall growth in rainforests, spongy roots and floating seeds in aquatic plants, and water storage in cacti.
It's Edible!
This document discusses fruits and seeds. It defines a fruit as a part of a plant that contains seeds. Fruits can be either soft and fleshy, like mangoes and watermelon, or hard and dry, like walnuts and coconuts. Nuts are classified as fruits that have a hard, inedible shell and seed. The document also defines a seed as the part of a plant that grows into a new plant, and provides examples of common seeds like sunflower seeds, pumpkin seeds, and bean seeds.

Temple of Asclepius in Thrace. Excavation results
The temple and the sanctuary around were dedicated to Asklepios Zmidrenus. This name has been known since 1875 when an inscription dedicated to him was discovered in Rome. The inscription is dated in 227 AD and was left by soldiers originating from the city of Philippopolis (modern Plovdiv).
LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.

Food Chain/ Food Web
- 2. Let’s recall • Animal’s habitats are grouped into: Terrestrial and Aquatic Habitats • Their adaptation can be based on structural and behavioral adaptation. • Other forms of adaptations are camouflaging, mimicry, hibernation etc. • All animals possess adaptive skill to survive in their habitats.
- 3. What can you say about this?
- 5. Learning goals * define food chain and food web • state the diet of different animals and why they eat them • group living things into producer, consumer and decomposer. • draw a simple food chain/food web
- 6. Key words • Producer • Consumer • Decomposer • Herbivore • Carnivores • Omnivores • Predators • Prey
- 7. Let’s watch and learn • https://www.youtube.com/watch?v=hLq2datP o5M
- 15. Trivia Time How is energy transferred in this food chain Producer Primary Consumer Secondary Consumer Prey Predator
- 16. 1. How many consumers are in this food chain? • at Answer: 4 2. Are there decomposers in this food chain? Answer: No. 3. What could have been their role? Answer: They breakdown the dead remains and turn it to nutrient in the soil
- 17. Today, we learnt • Food chain is the transfer of energy from one living thing to another • Food web is the network of food chains • Plants are the primary producers of food chain • Consumers are organisms that eat or consumes to get energy. • Decomposers breakdown dead remains of organisms and change it into nutrients
- 18. Do we have any question?
