Question

The Shannon diversity index is more useful than just a list of present species because...

a. It factors biomass into the index
b. It accounts for relative abundance and richness
c. It only factors species that are numerous enough to have a community level effect

d. It excludes microbes which tend to complicate diversity analysis

e. It calculates the exact number of species found in the habitat.

Answer 1

# Option (b) is correct

more favourable measure to account for species richness is Shannon diversity index than just listing species because"Shannon index accounts for both relative abundance and richness of a species"

Shannon index is a type of diversity index. A diversity index is a statistical measure to identify  all the diffrent species present in a community or dataset additionally taking into account the distribution of individuals or basic entities among these groups of species.
