Based on the intermediate disturbance hypothesis, a community's species diversity is increased by a. frequent massive disturbance. b. stable conditions with no disturbance. c. moderate levels of disturbance. d. human intervention to eliminate disturbance.

Verified step by step guidance

1. Step 1: Understand the Intermediate Disturbance Hypothesis. This hypothesis suggests that local species diversity is maximized when ecological disturbance is neither too rare nor too frequent. In other words, a moderate level of disturbance can increase a community's species diversity.
2. Step 2: Evaluate each of the given options in the context of the Intermediate Disturbance Hypothesis.
3. Step 3: Option a suggests frequent massive disturbance. This is not in line with the hypothesis, which suggests that too much disturbance can be detrimental to species diversity.
4. Step 4: Option b suggests stable conditions with no disturbance. This is also not in line with the hypothesis, which suggests that some disturbance is necessary for maximizing species diversity.
5. Step 5: Option d suggests human intervention to eliminate disturbance. This is not in line with the hypothesis, which suggests that some level of disturbance is beneficial. Therefore, the correct answer is option c, which suggests moderate levels of disturbance.
