What causes competition between two species? Select the TWO answers that are correct.

Question

Quizplus · Accepted Answer

Competition between two species usually arises when both species require the same limited resource, such as food, water, or shelter, that is either not sufficient or not divisible between them (option B). When two species do not have a way to partition a resource they both need, they may end up competing for it, leading to interspecific competition (option E). While option A describes an interaction between two species, it does not necessarily cause competition. Option C is incorrect because if the environment lacks a critical resource for one species, that species may not be able to survive, let alone compete with another species. Option D describes interspecific mating, which is not related to direct competition between two species.
