What makes up an ecosystem?

Answer and explanation

Correct answer: Living organisms and their environment

The correct answer is B: living organisms and their environment. An ecosystem is a functional system in which living organisms interact with one another and with non-living surroundings. Plants, animals, microorganisms and humans are biotic components. Air, water, soil, sunlight and temperature are abiotic components. Energy moves through the system, and materials are recycled through natural processes. A pond, forest or grassland can be an ecosystem because it contains organisms, physical surroundings and relationships between them. A computer, road or book may be present in an area, but none of these alone makes an ecosystem. Option B includes both essential parts, so it is correct. Memory cue: ecosystem means “living community plus its surroundings.”
