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.

C. The elevation changes of the mountain cause different climates.

Explanation:

The differences of altitude in the mountains allow a great diversity of climates that favor the diversification of species adaptable to different environments.

The climates and local differences determined by geomorphological, edaphic and vegetal cover features originate a range of microclimates that become habitats colonized by species that adapt to them and make up their specific niches.
