Which best describes niches? if two species have the same niche, one species will always become extinct. two species are able to occupy the same niche in the same habitat. two species cannot occupy the same niche in the same habitat. if two species have the same niche, one species will always move.

The correct answer is -

Two species cannot occupy the same niche in the same habitat.

Explanation:

Niche describes the set of environmental conditions where particular species lives within an ecosystem.

As per the Competitive exclusion principle (Gause's law) , two species cannot occupy the same niche in the same habitat for a long period of time.

If they do so, the organisms of both species will compete with one another for the same resources that are present in the environment and one will outcompete the other species, eliminating the other species.

Thus, two species cannot occupy the same niche in the same habitat.
