Gause's principle of competitive exclusion states that

Gause’s principle of competitive exclusion states that no two species can occupy the same ecological niche indefinitely for the same limiting resources. This is due to competition between the two species for resources, which ultimately results in the elimination of the inferior species from the habitat.
(2) Larger organisms always do not necessarily exclude smaller ones through competition. Competitively
Superior organism excludes the inferior organism.
(3) It is not always the case that more abundant species will exclude less abundant species through competition.
(4) Species with different food preferences can coexist without competition as they are not competing for the same
Resources.
