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

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
