Q. The Gause's 'Competitive Exclusion Principle' is true if: Answer:
resources are limited
Notes: 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 limited, but not otherwise. More recent studies do not support such gross generalisations about competition.
