The independent variable is? 12 Species 13 Claim 14 Higher Levels of Organization 15 Evidence 16 Biosphere Includes the living organisms (all the populations) in an area and the non-living aspects of the environment The role a species plays in the ecosystem. The size of the ecosystem under study The physical area where a species lives. All the living things in an ecosystem, such as plants and animals. Two or more populations of different species that live in the same area and interact with one another. Individual Organisms > Populations > Community > Ecosystem > Biosphere Explanation/answer based off of our experimental results OR observations of the some sort of phenomena (situation) Number of bacteria organisms living in the area Observations of the environment/situation AND/OR the data (observations) collected during experiment Population of Bacteria Includes most of Earth, including part of the oceans and the atmosphere with living organisms. A single individual from a species. A group of similar organisms that can breed and produce fertile offspring. A group of organisms that are all the same species. All the non-living things in an ecosystem, such as temperature, sunlight, and precipitation.
