An ecosystem consists of both biotic (living) and abiotic (non-living) components. This is true, as ecosystems are made up of living organisms, such as plants, animals, and microorganisms, as well as non-living components, such as water, air, and soil. Both biotic and abiotic components play important roles in the sustenance of life, as living organisms depend on non-living resources for survival, such as water, air, and nutrients from the soil. On the other hand, abiotic components, such as sunlight and climate, also influence the distribution and behaviour of living organisms in an ecosystem. The reason also supports the assertion, stating that biotic and abiotic components work independently in all ecosystems. This is because living organisms and non-living resources do not depend on each other, but instead interact in complex ways to sustain life in an ecosystem.
