Question
Biology Question on Population Interactions
Two different species can not live for long duration in the same niche or habitat. This law is
Allen's law
Gause's law
Competitive exclusion principal
Weiseman's theory
Gause's law
Solution
The correct option is (B) : Gause's law
Two or more species with the same needs cannot coexist in the same location for an extended period of time because they will eventually compete with one another for the resource. This is known as the Gause's Competitive Exclusion Principle, which states that established populations of more than one species cannot occupy an ecological niche concurrently and completely. However, two species cannot coexist in the same niche. The rivalry is fiercer the more similar the two niches are. Therefore, "Competitive exclusion principle" is the right response.
