1. BIOSPHERE

2. Four
Systems
of
Our
Earth

3. Composition of Earth
 Earth Has 4 main systems that interact:
Earth’s
systems
Atmosphere Hydrosphere Biosphere Geosphere
Air/gases water life land/rock

4. Composition of Earth
 Earth Has 4 main systems that interact:
 The Atmosphere
 The Hydrosphere
 The Biosphere
 Life on Earth
 Sea life, plants, flying creatures, humans
 Encompasses hydrosphere, upper geosphere, and
lower atmosphere.
 The Geosphere

5. BIOSPHERE

6. Living things interact with Non
living things in the Biosphere
 Biotic Factors—
living components
in the biosphere
 Biotic, meaning of
or related to life, are
living factors.
Plants, animals,
fungi, protist and
bacteria are all
biotic or living
factors.

7. Living things interact with Non
living things in the Biosphere
 Abiotic Factors—
nonliving
components in the
biosphere
 Environmental
factors such habitat
(pond, lake, ocean,
desert, mountain) or
weather such as
temperature, cloud
cover, rain, snow,
hurricanes, etc. are
abiotic factors.

8. Role of Water in the Biosphere
 Water is the
universal solvent
and the basis of
all life on our
Planet.
 The hydrosphere
is important to the
Biosphere!

9. Role of the Sun for the biosphere
 The Sun
provides the
light and heat
necessary to
maintain life
on Earth and
is the ultimate
source of
energy.

10.  Biotic and abiotic factors combine to create a
system or more precisely, an ecosystem.
 An ecosystem is a community of living and
nonliving things.

11. Grassland ecosystem

12.  Plants are
called
producers or
autotrophs
because they
are able to use
light energy to
make their own
food.

13.  Animals cannot make their own food so they
must eat plants and/or other animals. They
are called consumers or heterotrophs.
There are three groups of consumers.

14. To sum up:
Animals that eat
only plants.
Animals that eat
only animals.
Animals that eat
both animals AND plants
. Humans are also
omnivores!

15.  Herbivores are animals that only eat plants
or plant products (seeds). They are also
called primary consumers

16.  Carnivores are
animals that eat other
animals.
 There are 2 kinds of
carnivores

17.  Secondary Consumers
are carnivores that eat
herbivores
Herbivores are primary
consumers
Something that makes its
own food is called a
producer

18. Tertiary consumers are
carnivores that eat
other carnivores
 killer whales (tertiary
consumer—they eat
another carnivore)
 Dolphin (secondary
consumer—they eat a
herbivore)
 Herring (primary
consumer—they only eat
plants)
 Photoplankton (this
plant produces its own
food)

19.  Animalsand people who eat BOTH animals
and plants are called omnivores
WE EAT PLANTS WE EAT MEAT
