The process of mineralisation by micro organisms helps in the release of:a. inorganic nutrients from humusb. both organic and inorganic nutrients from detritusc. organic nutrients from humusd. inorganic nutrients from detritus and formation of humus. |
| Answer» MINERALIZATION is the RELEASE of inorganic substances, both non-mineral(e.g., CO2, H2O) and mineral(e.g., Ca2+, Mg2+, K+, NH+4) from organic matter. The process is slow because of trapping of these NUTRIENTS in humus and their immobilization in decomposers/detritivores. It prevents their washing out or LEACHING. Nutrients immobilized in decomposer microbes and detritivores are again exposed to humification and mineralization after the death of these organisms.So, the correct answer is 'Inorganic nutrients from humun | |
