• A. i only
• B. i, iii
• C. All
• D. ii, iii

Answer 1

Answer:

A. i only

• 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.
