The physical area where a species lives. A group of organisms that are all the same species. The size of the ecosystem under study Individual Organisms > Populations > Community > Ecosystem > Biosphere Includes the living organisms (all the populations) in an area and the non-living aspects of the environment A single individual from a species. All the non-living things in an ecosystem, such as temperature, sunlight, and precipitation. A group of similar organisms that can breed and produce fertile offspring. All the living things in an ecosystem, such as plants and animals. Explanation/answer based off of our experimental results OR observations of the some sort of phenomena (situation) Includes most of Earth, including part of the oceans and the atmosphere with living organisms. Population of Bacteria Two or more populations of different species that live in the same area and interact with one another.
