When two species compete, the niche that each species ultimately occupies is its realized niche.
Niche is the functional area of a species. This is the region where an organism actually lives, interacts with its biotic and abiotic factors and most importantly reproduces. Niche is a smaller part of the large habitat. Niche is of two types: Fundamental niche and realized niche.
