Solution

The correct option is C G. F. Gause
The ‘Competitive Exclusion Principle’ was proposed by Georgy Guase, a Russian biologist.

It states that two closely related species competing for the same resources cannot coexist indefinitely and the competitively inferior one will be eliminated eventually. This holds true if the resources are limited.

MacArthur gave the concept of resource partitioning. He showed that five closely related species of insectivorous birds called warblers that lived on the same tree were able to avoid competition and co-exist by choosing different times for feeding or different foraging patterns.

Verhulst - Pearl gave the logistic growth model.

Darwin gave the 'Theory of evolution by natural selection'.

Hence, the correct answer is option C.
