The concept of ecological niche was first introduced by Joseph Grinnell in 1917. A plant's or animal's niche, or more correctly, ecological niche, is a way of life that is unique to that species. Niche and habitat are not the same. While many species may share a habit, this is not true for a niche. Each plant and animal species is a member of a community. The niche describes the species' role or function within this community.
