5. Food Chain
once an organism uses the
energy from it’s food, it
stores the rest in it’s body
6. Food Chain
if one organism is removed
from the chain ALL the
other organisms in the
chain are affected
the organisms will die or
move away to survive
7. Food Chain – Example
Scenario
Say that all the caterpillars in a forest get
sick and die. The plants that the
caterpillars would have eaten may grow
and spread too much. They may use up
things such as water that other plants
need to live. The frogs that depend on
the caterpillars for food may die, too.
Then the snakes that eat the frogs to
survive will have less food. The snakes
may leave the forest to survive.
Organisms in other food chains in this
forest will also be affected.
8. Food Webs
a chain shows the flow
energy from one living thing
to the next in a straight line.
in nature though, it is more
complicated
9. Food Webs
several food chains
connect together to form a
food web.
like food chains
though, they start with the
sun
10. Food Webs
also like a chain, if one
organism is taken away, the
whole web is affected
12. In the previous food web,
grasshoppers are not the only
ones that eat plants. The
rabbits and small birds eat
them, too. They, in turn, are
eaten by both foxes and
hawks. The fungi and bacteria
get energy from wastes and the
remains of the plants and
animals when they die.
13. If you trace any of the animals
from the food web, you will
always end up where all food
chains and webs begin, with a
producer. No matter what an
animal eats, the energy in it’s
food began with a producer.
The producer then got it’s
energy from the sun.
