Answer :
When two species interact within a habitat, competitive exclusion can be observed when both species depend on same limiting resource and one species is better competitor for that resource.
what is competitive exclusion principle?
The principle of competitive exclusion states that two species competing for the same limiting resource cannot coexist at constant population values. If one species has the slightest advantage over another, the one with the advantage will dominate in the long run. This either leads to the extinction of the weaker competitor or to an evolutionary or behavioral shift to a different ecological niche. Competitive exclusion is rarely observed in natural ecosystems.
hence, if two species are inhabiting in same area then these will have same food requirement then competitive exclusion can be seen.
