Question

The mouse population in an area increases as the fox population decreases. C. The deer population on an island rises steadily and then levels out for many years. D. The population of geese in an area decreases when they migrate south for the winter.

Explanation
Competition for limited resources occurs when two or more organisms utilize the same set of scarce resources. This competition can limit the size of the population. Option A is about a population of grasshoppers destroying large fields of crops. This is not about competition for resources, but rather about the impact of a species on its environment.Option B is about the mouse population increasing as the fox population decreases. This is more about predator-prey relationships than competition for resources.Option D is about the population of geese decreasing when they migrate south for the winter. This is about seasonal migration, not competition for resources.Option C, however, is about the deer population on an island rising steadily and then leveling out for many years. This is a classic example of competition for limited resources. The deer population increases until the resources on the island (like food and space) can no longer support further growth, at which point the population levels out. This is a clear example of how competition for limited resources can affect the population of a species.
