Q. The process of mineralisation by microorganisms helps in the release of

Ecosystem

Solution:

Mineralisation is the release of inorganic substances, both non-mineral [e.g., $CO_{2}, H_{2}O$) and mineral (e.g., $Ca^{2+}, Mg^{2+}, K^{+}, NH_{4}^{+}$) from organic matter. The process is slow because of trapping of these nutrients in humus and their immobilisation in decomposers/detritivores. It prevents their washing out or leaching. Nutrients immobilised in decomposer microbes and detritivores are again exposed to humification and mineralisation after the death of these organisms.
