does not measure the number of individuals of each species
two communities may have the same species richness but one may be dominated by one species

Question 7

Answer 7

it takes into account the number of species present, as well as the abundance of each species

Question 8

why is it better to calculate an index of diversity rather than describing the species richness

Answer 8

species richness does not give indication of size of each population
