Answer

Correct option: A.

Both A and R are true and R is the correct explanation of A.

(a) Both A and R are true and R is the correct explanation of A.
Explanation: There are both biotic (living) and abiotic (non-living) elements in an ecosystem. This is accurate because ecosystems consist of both living and non-living elements, including soil, water, air, and other non-living things like animals, plants, and bacteria. Since living things depend on nonliving resources like water, air, and soil nutrients for survival, both biotic and abiotic components are crucial to the maintenance of life. On the other hand, abiotic factors like sunshine and climate also affect how living things are distributed and behave in an ecosystem. The justification, which states that biotic and abiotic elements function separately in every ecosystem, also bolsters the assertion. This is so that life can continue to exist in an ecosystem even while living things and non-living resources do not rely on one another.
