    Answer:

    A. i only

    Read Explanation:

    • Within an ecosystem, living organisms are categorized into different functional groups: producers (autotrophs like plants, which create their own food), consumers (heterotrophs like animals, which eat other organisms), and decomposers (like bacteria and fungi, which break down dead organic matter).

    • Therefore, it is incorrect to state that all living organisms are consumers, as producers and decomposers have distinct and vital roles in the ecosystem's functioning.
