FOOD CHAIN
Read the following story and use the information from the story to answer the
following questions.
 A student observes the following while on her camping trip in the forest:
 There are oak and maple trees and patches of grass and moss.
 She notices that there are rabbits and deer feeding on the grass and moss, and various
insects are feeding on the leaves of the trees.
 Birds start eating the insects, and she sees a hawk swoop down and eat a rabbit and
some birds.
 The bears in the forest often hunt for the deer and rabbits.
