1. Ecological Diversity: the richness and complexity of a biological
community, including the number of niches, trophic levels, and ecological
processes that capture energy, sustain food webs, & recycle materials
within this system.
2. Species Diversity: describes the number of different kinds of organisms
, within individual communities or ecosystems
3. Genetic Diversity: a measure of the variety of dif versions of the same
genes within individual species.
