There is a wild population of feral housecats on an island in southern Chile, which is feeding on a local penguin colony. They are the only predators on the island, and the penguins are the only prey. The intrinsic growth rate (r) of the penguins is 0.02. The capture efficiency (c) of the cats is 0.0003. Per capita mortality rates (m) in the cats are 0.1. And the efficiency that cats turn prey into offspring (a) is 0.08. Assume no delayed density dependence - a bit unrealistic, but a simplification.

Find the population numbers for both at which the net growth rate is zero for both (besides 0 cats and 0 penguins).

Group of answer choices

76 cats, 216 penguins
