Adiagram illustrates that grass is eaten by insects, birds, and mice. the insects are eaten by hawks, snakes, and toads. the birds and mice are eaten by foxes, hawks, and snakes. the toad is also eaten by the snake. which best describes the diagram?
a. pyramid
b. food chain grid
c. food web
d. trophic level

At first glance you can say that is B. a food chain grid. but if you look closely and see the type of animals eaten by others and that the descriptons include the words "also" we may see that is better to choose A. Pyramid which can explain not only a "chain" of eaters and eaten animals, but groups of animals that eat something similar. Hope this can help a lot
