Genetic diversity-genetic variation within a population and between populations
Species diversity-variety of species in an ecosystem
Ecosystem diversity-community interactions, extinction of one species has a negative impact on the species richness of the community

Habitat loss-single greatest threat to biodiversity
Introduced species-no natural predators so they outcompete native species
Overexploitation-human harvesting of wild organisms at rates exceeding the ability of populations to rebound
