Nutrients are retained in the ecosystem. Discuss how and name the process through which it is achieved?

Text Solution

Verified by Experts

Nutrients will retain in the ecosystem through biogeo chemical cycles.
Various nutrients present in soil and atmosphere enter the organism at various trophic levels through food and other process and are cycled back to their origin. Thus the nutrients are not lost but retained in the ecosystem.
