3. Genetic Diversity
The variety of genetic material available to a population
Resistance to outside influences

4. Ecological Diversity
The variety and distribution of ecosystems

5. Functional Diversity
The diversity of ways in which energy, water, carbon and nutrients move through an ecosystem

6. Species Diversity
The Number of species

7. Species Diversity Tropical Rainforests Greatest species diversity

10. Biodiversity Necessary for health and stability of ecosystems
All species are connected
All species have a niche
All play a role in the cycling of nutrients
Affects of altering food webs and ecosystems not easy to predict

11. Keystone Species
A species that is critical to the functioning of the ecosystem in which it lives
Prairie dog
Burrows provide shelter
Burrowing churns soil, sustains plant life
Foraging allows for more diverse plants species
Plant diversity sustains greater variety of animals
Food source for secondary consumers
