Question

competition is a/an exhausting concept. density - independent limiting factor. density - dependent limiting factor. irrelevant in evolution.

Explanation:

Competition is a density - dependent limiting factor. It depends on the population density as more individuals in a population lead to more competition for resources. It is not density - independent as its impact varies with population density. It is relevant in evolution as it drives natural selection. And it is not an exhausting concept but a well - studied ecological one.

Answer:

density - dependent limiting factor
