Which one of the following processes does NOT help in nutrient cycling?

Step-by-step solution

Nutrient cycling involves the movement and exchange of organic and inorganic matter back into the production of living matter. The processes involved include biological, geological, and chemical pathways. Photosynthesis and respiration are fundamental biological processes that drive the carbon cycle by fixing and releasing carbon dioxide, respectively. Decomposition is crucial for breaking down complex organic matter into simpler inorganic nutrients, returning them to the soil or atmosphere, thus driving the cyclin
