Ecological niche is a specific part of habitat occupied by individuals of a species, which is circumscribed by its range of tolerance, range of movement, microclimate, type of food and its availability, shelter, type of predator and timing of activity. A habitat has several ecological niches and supports a number of species. An ecological niche is used by a single species only. Two or more species cannot use the same niche.
