ecological principles
2 of 10
which of the following does not influence an organisms niche?
mutualism
commensalism
parasitism
competition with other species

Explanation:

Mutualism, commensalism, parasitism, and competition with other species all influence an organism's niche. A niche is an organism's role in its environment, and these ecological interactions affect how an organism obtains resources, interacts with others, and its overall position in the ecosystem. Since the question asks for what does NOT influence it, and all these are factors, there seems to be an error in the question's premise. But if we assume we must pick one, we note that mutualism is a positive - positive interaction, commensalism is positive - neutral, parasitism is positive - negative, and competition is negative - negative for the organisms involved. However, all of them shape the organism's niche.

Answer:

There is no correct option as all listed factors influence an organism's niche.
