    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.
