Moderate levels of disturbance refers to the factors which results in an increase in community diversity, which is based on the intermediate disturbance hypothesis.
<h3>What is Intermediate disturbance hypothesis?</h3>
This states that local diversity is maximized when the ecological disturbance of a given area is intermediate. Diversity on the other hand refers to the number of species present in an area over a given period of time.
The disturbance being too high or low will lead to adverse effects on the species which is why an intermediate effect will lead to an increase in the diversity of the species which are present in a given area. This is therefore the reason why it was chosen as the most appropriate choice.
