An animal that eats both plants and meat.
a. carnivore
b. herbivore
c. omnivore
d. producer
What is c. omnivore?

a. food web
b. energy pyramid
c. role
d. food chain
What is d. food chain?
Answers may vary but should relate to how producers take in the most energy but as that energy moves along the food chain, it reduces drastically with each time it is consumed.

b. director
c. consumer
d. decomposer
What is a. producer?
Explain why the term "food chain" is a good description of the relationships in this section.
(Answer may vary but will have something to do with how the sun's energy moves in a straight line as each animal is consumed, which creates the links)
