Which of the following would be a reason for a species to undergo cyclic population changes? The keystone species in its ecosystem is removed. The vegetation it eats increases and then decreases repeatedly with changing seasons. Its predator is preyed upon by a new species introduced to the ecosystem. Climate change alters the prevalence of parasites that affect the species.

    I agree that the correct answer is B [the vegetation...]. However, all the other answers could result in a decrease of the population of the specie (but it wouldn't be cyclic).
