| Food Chains: |
| A
food chain shows how energy goes from one living
thing to the other. When a mouse eats leaves or
grass it gets energy to live. A snake gets energy
from eating the mouse and a hawk gets energy from
eating a snake. The animals depend on each other
to get energy and live. If they don't have each
other they die. |

|
| Food Webs:
|
| A
food web shows more detail about how animals get
energy. For example: The hawk eats snakes,
rabbits and small animals. The snake eats mice
and frogs and other rodents. The mouse eats
leaves and grass and other plants for energy. The
plants get their energy from sunlight and water. |

| The Delicate Balance
of Organisms: |
| If
a species is changed or eliminated from the food
web it will have an effect on other species. Each
species depends on certain other species for
energy and survival. A small change can have a
big impact on all other species. |
