ecological niche

The place or function of a given organism within its ecosystem.

Note

Different organisms may compete for the same niche. For example, in a forest there may be a niche for an organism that can fly and eat nectar from blossoms. This niche may be filled by some sort of bird, or an insect, or even a mammal such as a bat.
