Question

Based on the intermediate disturbance hypothesis,a community's species diversity is increased by
A)moderate levels of disturbance.
B)frequent natural disasters of large magnitude.
C)stable conditions with small fluctuations.
D)human-caused disturbances such as clear cutting and burning.
E)A and C

Accepted Answer

According to the intermediate disturbance hypothesis, moderate levels of disturbance can create a more diverse community by allowing for coexistence of various species that are adapted to different levels of disturbance. Too little disturbance can result in competitive exclusion, while too much disturbance can lead to the dominance of a few, highly adapted species. Therefore, option A - moderate levels of disturbance - is the best choice.
