Ecology Ch 3 Section 3 The Ecosystem Ecosystem Highly organized structure Many interactions Some obvious and some subtle Delicate balance Can be studied at many levels Individual Population Community Ecosystem Species Group of organisms that can produce fertile offspring Often have similar needs Leads to competition for resources Where they live is their habitat Area is the geographic range Loss of the above can have a negative affect on species Populations and Communities Population is all of the members of a species in a given area. Pheasant population in Faribault Co. White-Tail deer population in MN Squirrel population in my backyard Community- All of the species that live and interact in a given area Forest community Wetland community Ecosystems Ecosystem- All of the communitites along with the environment (abiotic) Includes water, soil, rocks, weather, etc Biodiversity can indicate health of ecosystem Echoes of Cry of the Marsh Video that refers back to an older video shot in MN History of habitat destruction and results Not just the rainforests!
