Question

6 multiple choice 1 point which outcome describes competitive exclusion? both species share the resource equally populations expand indefinitely one species eliminates another from accessing a resource species evolve identical niches

Explanation:

Competitive exclusion principle states that two species competing for the same limited resource cannot coexist at constant population values. One species will out - compete the other, leading to the elimination of the weaker competitor from accessing the resource.

• "Both species share the resource equally" is not competitive exclusion. In competitive exclusion, there is no equal sharing as one species is excluded.
• "Populations expand indefinitely" is not related to competitive exclusion. Competitive exclusion is about competition for resources and one species being excluded, not population expansion.
• "Species evolve identical niches" is not competitive exclusion. In fact, if species have identical niches, competitive exclusion is more likely to occur, but the description of the principle is about one species eliminating another from a resource.

Answer:

One species eliminates another from accessing a resource
