Organization of Ecosystems
Segment: 9. Natural Resource Systems, Standard: Apply scientific principles of an ecosystem. (Technical III.A.2)
Ecosystems are organized to better understand the frame of reference in which they are being studied. They are organized from smallest to largest; organism, population, community, ecosystem. An organism is a single living thing, a population is all of the organisms of the same species in the same place at the same time, a community is all populations in the same place at the same time (all living things), and an ecosystem is the reactions between living and nonliving components in a given area. Ecosystems can vary in size depending on the scope of study.
