Gause's principle of competitive exclusion states that:
Options
- AMore abundant species will exclude the less abundant species through competition
- BCompetition for the same resources excludes species having different food preferences
- CNo two species can occupy the same niche indefinitely for the same limiting resources
- DLarger organisms exclude smaller ones through competition
Correct answer
C. No two species can occupy the same niche indefinitely for the same limiting resources
Step-by-step solution
It is a proposition named after Georgy Gause. Gause's principle of competitive exclusion states that two closely related species competing for the same resources cannot c0-exist indefinitely and the competitively inferior one will be eliminated eventually. This may be true if limited resources are present.
