ANSWER

Biodiversity index = 0.096

EXPLANATION

Given 7 different organisms with their individual numbers.

Biodiversity Index is:

$\text{ }\frac{Total\text{ number of species}}{Total\text{ number of individuals in the area}}$

i.e:

$\begin{gathered} Biodiversity\text{ Index = }\frac{7}{15+2+30+1+4+16+5} \\ \text{ = }\frac{7}{73} \\ \text{ = 0.09589} \end{gathered}$

Hence, the Biodiversity Index of Fraya's local park is 0.096. This is a low biodiversity since it's closer to 0.
