An ecosystem is best described as?

An ecosystem is best described as?

• A. A single organism
• B. A community of organisms considered in relation to each other and their environment
• C. The climate of a region
• D. A laboratory feeder system

Answer: (B)

An ecosystem is a community of organisms interacting with each other and with the nonliving part of their environment, with energy flowing through and nutrients cycling among them. This description fits best because it captures both the living relationships and the surrounding environment that all together make up an ecosystem, from plants and animals to climate, water, and minerals. A single organism by itself isn’t the whole system, since it doesn’t include the relationships with other organisms or the environment. The climate refers to weather conditions, not the living community. A laboratory feeder system is an artificial, controlled setup rather than a natural, interacting community in a real environment.
