Topic 1 Interactions Within an Ecosystem

I. Interactions Within an Ecosystem Ecology is the study of the relationship between living organisms and their environment An ecologist is someone who studies these relationships

A. The Needs of Living Things 1. Living things need food 2. Living things need water

3. Living things need a suitable habitat 4. Living things exchange gases Plants need carbon dioxide and produce oxygen Animals need oxygen and produce carbon dioxide

B. Adaptations An inherited characteristic that enables an organism to survive and reproduce in an environment How an organism adjusts to “ fit in ” Some are learned during an organism ’ s lifetime
