Question

I need help with this practice, read below then read the picture Amy found 6 species in her backyard, she wrote down the names of the species and how many she found for each;Ruby throated hummingbird / 9 individuals Blue jay / 6 individuals Dandelions / 43 individuals Chipmunk / 3 individuals Cooper’s hawk / 3 individuals Red bellied woodpecker / 2 individuals

Answer 1

Biodiversity index = 0.091

Step-by-step explanation

Given a total number of 6 species with their individual numbers

Biodiversity index is:

`\text{ }\frac{Total\text{ number of species }}{Total\text{ number of individual in the area}}`

i.e:

`\begin{gathered} Biodiversity\text{ index = }(6)/(9+6+43+3+3+2) \\ \text{ = }(6)/(66) \\ \text{ = 0.09090} \end{gathered}`

Hence, the Biodiversity index of Amy's backyard is 0.091. This indicates a low biodiversity since it's closer to 0.
