Question 3

What Is The Formula For The Index Of Diversity (D) & What Do Each Of The Letters Represent?
(4 Points)

~ N = Total number of organisms, of a single species, in the community.

~ n = Total number of organisms, in the community.

~ Σ = Sum of.

Question 4

What Are The Steps Contributing To The Index Of Diversity?
(3 Points)

Answer 4

1) Calculate N(N-1) to find value A.

2) Calculate n(n-1) for each species and add all these numbers together to find value B.

3) Divide value A by value B.

What Does A Higher Diversity Index Indicate?

Answer 5

A more diverse area.

Question 6

What Does An Index Of 1 Mean?
