Question

State whether the following statement is true or false:

An ecosystem is not a self-sufficient unit.

Answer 1

This statement is false.

Explanation:

An ecosystem is a self-contained unit because it consists of a biotic community (living organisms such as producers, consumers, and decomposers) and its abiotic environment. There is a cyclic exchange of materials between living beings and the environment, ensuring continuity. The only external requirement for an ecosystem’s sustenance is a constant energy input, primarily from sunlight. This allows the ecosystem to function independently as a whole system. Thus, ecosystems are self-sufficient units that require energy input but maintain internal material recycling.
