Question

Measuring biodiversity in a community can help ecologists predict the stability of an ecosystem. More biodiverse communities can make ecosystems more resilient to changes from natural or human origin. Calculate the Simpson's Diversity Index for a community with the following species distribution:

81 pine trees
19 oak trees
10 maple trees
A) 0.22
B) 0.42
C) 0.58
D) 0.81

Answer 1

.42

Step-by-step explanation:

When you divide each of the individual species by 110, you then square the answer. These answers are then added (summed) together. This gives you 0.58. However, the last step requires you to subtract that from 1. This gives you 0.42.

Answer 2

the answer is B) 0.42

Step-by-step explanation:

When you divide each of the individual species by 110, you then square the answer. These answers are then added (summed) together. This gives you 0.58. However, the last step requires you to subtract that from 1. This gives you 0.42.
