However, Realized niche covers only those conditions which are in actual used by a specific organisms while interacting with other organisms. Fundamental and realized niches can be wide or narrow. If resources are limiting, two species normally cannot occupy the same niche indefinitely. May 20, 2017 By Rachna C 1 Comment. Habitat is a set of the place of environmental conditions in which particular organism lives and adapt the situation accordingly. The main difference between fundamental niche and realized niche is that the fundamental niche is any type of environmental condition in which a particular species can live whereas the realized niche is where the species actually live.In a fundamental niche, there is no competition for resources or predators while in a realized niche, there is a competition for both resources and predators. The main difference between a fundamental niche and a realized niche is the chances of survival of a species in a fundamental niche is expected to be higher than in a realized niche. Workplace is an example of fundamental niche whereas manager, assistant, executive, and peon are the examples of realized niche.

For example: Competition for food and resources, predation to get food etc. A fundamental niche is the range of conditions and resources an organism could use. Therefore, it is quite evident that Fundamental niche is larger in size than realized niche… Describe what differentiates realized and fundamental niches Identify factors that determine a species' ecological niche ; Practice Exams.
