The number of species in a community is known as species diversity.

• True

• False

Answer explanation

The number of species in a community is known as species richness. Species diversity takes species richness into account, but it also includes a measure of the evenness of the abundance of the different species. The more species there are and the more evenly the number of organisms is distributed among the different species, the greater the species diversity.
