Species facing competition might evolve mechanism that promotes coexistence rather than exclusion. Justify this statement in light of Gause' s competitive exclusion principle, citing suitable examples.

Explanation

Gause.s .Competitive Exclusion Principle. states that two closely related species competing for the same resources cannot co-exist indefinitely and the competitively inferior one will be eliminated eventually. This may be true if resources are limiting, but not otherwise.
More recent studies do not support such gross generalizations about competition. While they do not rule out the occurrence of interspecific competition in nature, they point out that species facing competition might evolve mechanisms that promote co-existence rather than exclusion. One such mechanism is .resource partitioning..
If two species compete for the same resource, they could avoid competition by choosing, for instance, different times for feeding or different foraging patterns.
MacArthur showed that five closely related species of warblers living on the same tree were able to avoid competition and co-exist due to behavioral differences in their foraging activities.
