Which of the following statements correctly identifies aspects used to describe ecosystem structure?

  1. Ecosystem structure can be detailed by examining its trophic organization and the composition of species present.
  2. The consideration of size scale and clear boundaries are irrelevant when describing an ecosystem's structure.
  3. Stratification, which refers to the vertical layering of an ecosystem, is a key component in understanding its structure.
  4. Only the living components are used to describe an ecosystem's structure; abiotic factors are excluded.

    A1

    B2, 4

    C1, 3

    Dഇവയൊന്നുമല്ല

    Answer:

    C. 1, 3

    Read Explanation:

    • Ecosystem structure is a multifaceted concept that goes beyond simply listing organisms.

    • It encompasses how these organisms are organized, their relationships (trophic levels), the variety and abundance of species, and how they are distributed vertically (stratification).

    • Furthermore, understanding the physical dimensions (size scale) and the limits (boundaries) of an ecosystem helps define its unique characteristics and functioning.
