Definition of Competitive Exclusion

Competitive exclusion principle is a phenomenon that states that the two species cannot co-exist in the population if they are competing for the same limiting resources. The species tend to dominate over the other for a long time if that has got a slight advantage over the other and afterwards take complete control of its habitat.


Resultantly, the species which dominates becomes the reason for the extinction of the other species and there would be no more competition between the species now and the niche of both the species become separated. The three potential results of competition between the species are competitive exclusion, extinction, and differentiation.
