Gause’s principle of competitive exclusion states that:

1. more abundant species will exclude the less abundant species through competition.
2. competition for the same resources excludes species having different food preferences.
3. no two species can occupy the same niche indefinitely for the same limiting resources.
4. larger organisms exclude smaller ones through competition.

Correct answer: no two species can occupy the same niche indefinitely for the same limiting resources.

Solution

Gause’s competitive exclusion principle says that two species cannot stably coexist if they occupy the same niche and depend on the same limiting resources. Over time, one species will outcompete the other, preventing indefinite coexistence.
