Which are the only two interaction types to depend on density and effective defense to determine the short-term impact?
A)competition and consumption
B)consumption and parasitism
C)parasitism and mutualism
D)mutualism and commensalism

Question

Quizplus · Accepted Answer

Consumption and parasitism are the only two interaction types that depend on density and effective defense to determine the short-term impact. In consumption, the predator’s effectiveness is determined by prey density, while in parasitism, the parasite's effectiveness is determined by the host's density and its ability to defend against the parasite. The other interaction types, such as competition, mutualism, and commensalism, do not depend on density and effective defense to determine their impact.
