| Food Webs and
Chains |
| Food
Chains: |
| A food
chain is a chain of organisms that eat other
organisms. Organisms are whole living substances
that live of from other organisms. The arrows
point to what eats the animal at the beginning of
the arrow. Food chains don't show the "Big
Picture" because they only tell you one
predator that the prey has, and they only tell
you one prey the predator has. |

| Food
Webs: |
| A food
web is a community of organisms where there are
several interrelated food chains. There are
various roles that organisms take in a food web
here are some examples. A producer is an organism
that makes it's own energy. A first-level
consumer eats the producer, the second-level
consumer eats the first-level consumer, and the
third-level consumer eats the second-level
consumer. |

| The
Delicate Balance of Organisms: |
| If the
population of a population of a species decreaces
or increases the whole way of life in the Amazon
for animals goes out of whack. For instance if
the snake population doubled the frog population
would decrease and the fly population would
increase because the frogs were not the same
number as they were before the snakes population
increased. Also with the habitat of the animals
of the Amazon getting destroyed there are fewer
places for them to live and more and more of the
species are decreasing and setting the food chain
out of balance. |
