Why are there many niches of species in one mountain?

A. The leeward and wayward sides of the mountain have different elevations. B. There's no water on the top of a mountain to support life. C. The elevation changes of the mountain cause different climates. D. The biotic factors on the mountain force interspecific competition.

Answer: Option D

Explanation:

In interspecific competition two species use the same resource that is found at a particular place in a limited amount.

A niche is can be defined as a place which defines a set of conditions, resources and interactions it needs.

This states that one mountain can have many niches as more than two species compete for the same biotic resource.
