Question

Quizplus · Accepted Answer

Competition can constrain the realized niche occupied by an organism by limiting its access to resources such as food, water, and shelter. In an environment where there are many species competing for the same resources, each species may occupy a narrower niche to avoid direct competition with other species. This can result in a species occupying a suboptimal niche or even completely changing its behavior or morphology to reduce competition.
