How does an ecosystem differ from a community?
An ecosystem refers to the community and its abiotic environment, whereas a community refers to all populations in a set area.
Communities are made up of multiple populations in a specific area at a specific time. (A population refers to individuals in a specific species in a specific area at a specific time.) You can learn about the community of life living in the arctic circle during the month of December for example.
An ecosystem is a broader classification. An ecosystem is composed of the community and its abiotic environment. Thus, the arctic circle ecosystem includes the life there but also the snow, the ice, the effects of the sun, the rocks, and so forth. Learn more about the arctic ecosystem here .
