Detailed explanation-1: -Interspecific competition often leads to extinction. The species that is les s well adapted may get fewer of the resources that both species need. As a result, members of that species are less likely to survive, and the species may go extinct.

Detailed explanation-2: -The competitive exclusion principle is an ecological principle stating that when two competing life forms attempt to occupy the same niche, only one outcome is possible: One life form will drive out the other.

Detailed explanation-3: -When one species has even the slightest advantage over another, the one with the advantage will dominate in the long term. This leads either to the extinction of the weaker competitor or to an evolutionary or behavioral shift toward a different ecological niche.

Detailed explanation-4: -The competitive exclusion principle says that two species can’t coexist if they occupy exactly the same niche (competing for identical resources). Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.

Detailed explanation-5: -The four outcomes of this model are: 1) species A competitively excludes species B; 2) species B competitively excludes species A; 3) either species wins based on population densities; or 4) coexistence occurs. Species can survive together if intra-specific is stronger than inter-specific competition.
