Humification.lt is the process by which simplified detritus gets converted into dark coloured amorphous substance, the humus (humis : substances) in the soil. It is relatively a rapid process than mineralization’ Mineralizatio. It is . release of organically bound nutrients into an inorganic form (i.e., minerals) available to plants This slow process is performed by decomposers existing in soil and feeding on humus (Odum and Barrett, 2005).
Humus is partially decayed organic matter. It makes soil porous, thereby increasing its air and water holding capacity. It is rich in nutrients (e.g., minerals) that promote plant growth. Being black or dark brown in colour, humus absorbs heat to warm up the soil.

The phenomenon of increase in the concentration of harmful non-biodegradable substances in the body of living organisms at each trophic level of the food chain is called bio magnification. Two heavy metals which are biomagnified are mercury and cadmium.

Humus is partially decayed organic matter. It makes soil porous, thereby increasing its air and water holding capacity. It is rich in nutrients (e.g., minerals) that promote plant growth. Being black or dark brown in colour, humus absorbs heat to warm up the soil.

The whole process of weathering of rocks involving living organisms is called biological weathering, e.g., Lichens, mosses, herbs, shrubs and trees.
