if all the grass disappeared from this community, which change would be most likely to occur?
a. the cougar population would stay the same.
b. the coyote population would increase.
c. the squirrel population would decrease.
d. the deer population would decrease.

Explanation:

Grass is a food - source for the squirrel in this food - web. If grass disappears, the squirrel population, which depends on it for food, is likely to decrease due to lack of sustenance. The cougar population may be affected as its prey sources could change, but not directly as it doesn't eat grass. The coyote population is also not directly dependent on grass as a food source. The deer has other food sources like mushrooms and acorns in addition to grass, so its decrease is not as certain as the squirrel's.

Answer:

C. The squirrel population would decrease.
