Which of the following statements accurately describes the fundamental nature of an ecosystem?

  1. An ecosystem is essentially a static collection of living organisms isolated from their surroundings.
  2. It can be conceptualized as a specific area of land or a water-body where life processes occur naturally and continuously.
  3. Structurally, an ecosystem exclusively comprises a community of various living organisms without considering non-living factors.
  4. The core structure of an ecosystem involves a community of living organisms interacting with their abiotic environment.

    D. ii, iv

    Read Explanation:

    • An ecosystem represents a dynamic interplay between biotic (living) and abiotic (non-living) components within a defined area.

    • It's not merely a collection of organisms but a self-sustaining unit where energy flows and matter cycles, allowing life to continue naturally.

    • This holistic view emphasizes the interdependence between living beings and their physical surroundings.
