Quizplus · Accepted Answer

An ecological niche refers to the role and position a species has in its environment, including all its interactions with the biotic and abiotic factors. It encompasses how a species meets its needs for food and shelter, how it survives, and how it reproduces. A key concept in ecology is that two species cannot occupy the exact same niche in the same environment for a long time because one will outcompete the other, a principle known as competitive exclusion.
