If all the plants in a habitat suddenly died, what would happen to the animals? A.
The animals would plant new plants.
B.
The animals would start eating rocks.
C.
The animal population would grow because they would have more space.
D.
Animals that could not leave would also die after some time.

D. Animals that could not leave would also die after some time.

Explanation:

A is incorrect because animals aren't like humans, and most likely don't know how to plant and grow new plants. B is incorrect because no animal eats rocks. C is incorrect because even though they have "more space", they don't have any plants to eat so they would die off. This leaves answer D which is correct because they would die off as well. Plants and animals depend on each other.
