Process in which detritus are degraded into simple inorganic substances using bacterial and fungal enzymes is called
1 Catabolism
2 Fragmentation
3 Leaching
4 Humification
Explanation:
Catabolism is a process under decomposition. In catabolism the decomposers excrete digestive enzymes over the detritus. It changes insoluble complex organic substance into inorganic compounds

A detrivorous animal of economic importance is:
1 Caterpillar larva
2 Leech
3 Earthworm
4 Giriraja fowl
Explanation:
The earthworms improve the fertility of soil in different ways and, therefore, they are of utmost importance in agriculture. Actually, the borrowing and soil feeding habits of earthworms make the soil porous which permit both aeration and quick absorption of water. It also permits easy and deep penetration of the plant roots.

The process of breaking down complex organic matter into its basic inorganic substances is called
1 Humification
2 Mineralisation
3 Decomposition
4 Leaching
Explanation:
Decomposers break down complex organic matter into inorganic substances like carbon dioxide, water and nutrients and the process is called decomposition.

The process of mineralisation by micro organisms helps in the release of:
1 Inorganic nutrients from humus
2 Both organic and inorganic nutrients from detritus
3 Organic nutrients from humus
4 Inorganic nutrients from detritus and formation of humus.
Explanation:
Mineralisation by organisms helps in formation of inorganic nutrients from Humus.

Identify the false statement regarding the decomposition
1 Detritus is the raw material for decomposition
2 Decomposition is oxygen requiring process
3 Precipitation of soluble inorganic nutrients into the soil horizon as unavailable salts is mineralization
4 Warm and moist environment favors decomposition
Explanation:
option 3 is the definition of leaching, Mineralisation will result in release of inorganic substances and available nutrients into the soil.
