Question

which of the following does not influence an organism’s niche? mutualism competition with other species parasitism commensalism

Explanation:

An organism's niche is influenced by its interactions with other species. Mutualism, parasitism, commensalism, and competition are all types of species - species interactions that shape a species' niche. However, since the question asks for what does NOT influence it, and none of these options truly does not influence it, this might be a mis - phrased question. But if we assume the intent is to find the least direct influence among these, competition with other species is more about resource acquisition and survival in a shared environment rather than directly defining the unique role (niche) in the ecosystem compared to the symbiotic relationships (mutualism, parasitism, commensalism) which are more about the nature of the interaction itself.

Answer:

Competition with other species
