Answer

Species richness and relative abundance.

Work Step by Step

Both the number of individual species and their relative proportions are taken into account when comparing diversity levels. When comparing two communities with the same number of species (species richness), the proportions of these populations (relative abundance) are then taken into account. More species with somewhat even proportions between them is the ideal situation for species diversity.
