Question

Given below are two statements:

Statement I: Gause's competitive exclusion principle states that two closely related species competing for different resources cannot exist indefinitely.

Statement II: According to Gause's principle, during competition, the inferior will be eliminated. This may be true if resources are limiting.

In the light of the above statements, choose the correct answer from the options given below:

Options

A.Statement I is true but Statement II is false.
B.Statement I is false but Statement II is true.
C.Both Statement I and Statement II are true.
D.Both Statement I and Statement II are false.

Solution

Sol. [Key Concept: Competitive exclusion]

Statement I is false because the principle concerns species competing for the same limiting resources, rather than different resources. Statement II gives the intended outcome: the competitively inferior species may be excluded under the stated limiting conditions. Resource partitioning can allow coexistence. Hence, option (2).
