All the living organisms are basically made up of C, N, S, P, H and O. How do they enter the living forms? Discuss.


Through photosynthesis and absorption from soil. A nutrient cycle (or ecological recycling) is the movement and exchange of organic and inorganic matter back into the production of living matter. The process is regulated by food web pathways that decompose matter into mineral nutrients. Nutrient cycles occur within ecosystems. Ecosystems are interconnected systems where matter and energy flows and is exchanged as organisms feed, digest, and migrate from one place to another.
