Nutrient cycle is the biogeochemical cycle that<span> includes exoskeleton and shells of marine organisms as a reservoir. This cycle involves the exchange of organic and inorganic matter back to the living production of matter. The decomposition of exoskeleton and shells of marine organisms will give nutrients which will be used in this cycle.</span>
