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 is eliminated eventually. This may be true if resources are limiting, but not otherwise. Mechanism of 'Resource partitioning' states that if two species compete for the same resource, they could avoid competition by choosing, for instance, different times for feeding or different foraging patterens.
