    Answer:

    A. iii, iv

    Read Explanation:

    • An ecosystem is a complex system where living organisms (biotic components) interact with non-living physical and chemical elements (abiotic components).

    • This continuous interaction, such as plants using sunlight and soil nutrients, or animals consuming plants and contributing to nutrient cycling through waste, drives energy flow and nutrient cycles, which are fundamental to sustaining life within that environment.

    • Without the interplay between these two fundamental parts, an ecosystem cannot function or maintain its delicate balance.
