The competitive exclusion principle states that
a. more than two organisms are capable of filling the same niche
b. competition between species never leads to exclusion
c. two organisms who attempt to fill the same niche will develop a mutualistic relationship
d. when two organisms attempt to fill the same niche, one will exclude the other from the ecosystem

The competitive exclusion principle states that when two organisms attempt to fill the same niche, one will exclude the other from the ecosystem. Research partitioning is an adaptive evolution that when species are have similar preys, they compete with each other and one species is deemed to extinct in the process however if two species are of different preys, then they can exist with one another. To exist with one another, organisms belonging to a same species either compete for the resources or divide it amongst themselves. This concept is important because it helps in diversified ecology, where animals and plants of the same species co-exist and creates a beauty with nature.
