Clarifying ?s Information Page # habitat - place where organisms obtain food, H2O, shelter, and all other things needed to live, grow, and reproduce Living Organisms and the Environment abiotic factors- the non-living parts of an ecosystem Examples: water, sunlight, oxygen, temperature, soil biotic factors- the living parts of an ecosystem Examples: people, animals, plants population- the members of a single species in a given area. The area can be big or small - contained or not contained Example: (contained) Texas prairie dog - prairie dog town Example: (not contained) finback whale - whole ocean community - all populations that live together - They live close together and interact. Example: prairie dogs and quail ecosystem- the combination of the community and abiotic factors ecology - the study of how living things interact with each other and their environment Summary:
