Answer 1

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}} \\ =(6)/(67) \\ \approx0.0896 \end{gathered}`

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