Two components of biological diversity that we consider in lab 1? a. b. These are the components of species diversity and are known widely from field work. Genetic diversity is much less known, but knowledge of it is growing rapidly. Ecosystem diversity is part and parcel of biogeography, that we will begin to study next in terms of the biomes of the terrestrial earth.

The two components of species diversity, from your lab exercise. a. Species richness, number of species. b. Relative abundance.
