A national park is home to large populations of mountain lions, deer, rabbits, and grass. Recently, park rangers decided to introduce wolves to the park. Mountain lions and wolves both eat deer and rabbits. Deer and rabbits both eat grass. Based on the information provided, if the number of deer and rabbits eaten by the mountain lions stays the same, what can the park rangers predict will happen to the grass after wolves are introduced?

A.
The amount of grass will decrease until it is all gone, because the deer and rabbit populations will continue to consume it.

B.
The amount of grass will decrease, but some will remain, because the mountain lions and wolves will not consume it anyway.

C.
The amount of grass will stay the same, because the deer and rabbit populations will remain unchanged.

D.
The amount of grass will increase, because the deer and rabbit populations will decrease due to increased predation.
