4.1.3 - Comparing Biodiversity Between Habitats Flashcards
What Can Be Used To Measure Species Diversity?
Index of diversity.
What Does The Index Of Diversity Measure?
(2 Points)
~ Number of species present in a community.
~ How each species contributes to the total number of organisms in that community.
What Is The Formula For The Index Of Diversity (D) & What Do Each Of The Letters Represent?
~ N(N-1) / Σn(n-1)
~ N = Total number of organisms.
~ n = Total number of organisms of each species.
~ Σ = Sum of.
What Are The Steps Contributing To The Index Of Diversity?
(3 Points)
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?
A more diverse area.
What Does An Index Of 1 Mean?
(2 Points)
~ All the individuals are of the same species.
~ No biodiversity.
