What three factors does a species diversity index take into account?

a. Species richness, species diversity, and species productivity

b. Species richness, species abundance, and species evenness

c. Species evenness, species abundance, and species stability

d. Species abundance, species stability, and species richness

e. Species productivity, species stability, and species richness

Answer: b. Species richness, species abundance, and species evenness.

Explanation:

The species diversity index can be define as the measure of diversity of species. This takes into account for the number of species present in an area, also the relative abundance of species in an area. If the species richness increases, evenness of the species also increases and the diversity of species also increases.
