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.

The degrees of freedom can be used to test a hypothesis about the mean.
<h3>What is degrees of freedom?</h3>
Degrees of freedom refers to the maximum number of logically independent values that have the freedom to vary, in the data sample.
Given, the sample size is 20, then degree of freedom will be
The degrees of freedom represented as
dof = n – 1
dof = 20 – 1
dof = 19
Thus, the degrees of freedom can be used to test a hypothesis about the mean.
