ECOLOGY Ecology is: The study of the relationship between living organisms and their environment. In other words—Ecology is the study of Ecosystems. • An ecosystem is an interacting system of Living (biotic) organisms and their non-living (abiotic) environment. An ecosystem is made up of two sets of factors: • A) biotic factors—the living portion of the ecosystem. Living organisms such as plants, animals, fungi, and the list goes on. Ecological Organization The organization of ecological factors is as follows: 1. Individual 2. Population 3. Community 4. Ecosystem • Individual- one organism • Populations: Group of organisms of the same species living in an area. • Communities—all of the living organisms in an ecosystem. B) Abiotic factors—the non-living portion of the ecosystem. This includes the following: • Water • Soil • Temperature • Sunlight In order for an ecosystem to exist it must meet 3 criteria to be SELF-SUSTAINING: • HAVE AN ENERGY SOURCE (SUN) • ENERGY MUST BE CONVERTED OR STORED FOR USE BY ORGANISMS • NUTRIENTS MUST BE RECYCLED YOU DECIDE— ENVIRONMENT OR ECOSYSTEM?
