C)character displacement.
D)resource partitioning.

Question

Quizplus · Accepted Answer

The competitive exclusion principle states that two species competing for the same limiting resource cannot coexist at constant population values. Therefore, the elimination of one new species by another due to direct competition for the same resources is an example of the competitive exclusion principle. Intraspecific competition refers to competition between individuals of the same species, and is not relevant to the scenario described. Character displacement and resource partitioning are mechanisms that can allow for coexistence of species in a shared ecosystem, but they are not applicable in this scenario.
