Answer 1

Answer:

0.0896

Explanation:

First, calculate the total number of individuals.

$Total=9+6+44+3+3+2=67$

The number of species = 6.

Using the formula given for Biodiversity Index:

$\begin{gathered} \text{ Biodiversity Index}=\frac{\text{Total number of species}}{\text{ Total number of individuals in the area}} \\ =\frac{6}{67} \\ \approx0.0896 \end{gathered}$

The biodiversity index is approximately 0.0896 correct to 4 decimal places.
