Lymphatic System
Variety of species in an ecosystem.
Species Diversity
More species, greater stability.
Ecosystem stability
Maximizes resource use.
Ecosystem productivity
Pollination, water purification, soil fertility, medicine.
Ecosystem services
More species = more genetic variety.
Genetic diversity
