Species diversity has two components:
- A
Habitat richness (number of biomes) and habitat evenness (relative area)
- B
Genetic richness (allele variation) and genetic evenness (allele frequency)
- C
Trophic richness (number of levels) and trophic evenness (energy per level)
- Dcheck_circle
Species richness (number of species) and species evenness (relative abundance)
Explanation
Two communities can have the same richness but very different evenness; both contribute to overall diversity.
