ecological niche 1. The space occupied by a species, which includes both the physical space as well as the functional role of the species. 2. Ecological niche refers to the characteristics of an environment that provides all the essential food and protection for the continued survival of a particular species of flora or fauna. In addition to food and shelter, there is no long-term threat to existence in that place from potential predators, parasites and competitors. The concept of the ecological niche goes a long way beyond the idea of the species habitat
