An ecosystem has 150 organisms of 15 different species. What is the biodiversity index of this ecosystem?
iren2701 [21]

Answer:

0.1

Explanation:

To calculate this, scientists use a formula called the biodiversity index in order to describe how much are the species of a given area diverse. It is calculated by taking the number of species in the area and divided by the total number of individuals in that area. This gives us the biodiversity index.

In this example, there are 15 species in an area and we divide that by 150 organisms to get a 0.1 biodiversity index.
