Earthworms are regarded as farmer's friends because
1 They help in fragmentation of detritus and loosening of soil
2 They help in leaching
3 They reduce the rate of decomposition
4 All of them
Explanation:
Earthworms are regarded as farmer's friends because they help in fragmentation of detritus and loosening of soil, also the feacal matter - vermicompost is rich in nutrients.

Word detritus includes
1 Dead plant parts
2 Dead animal parts
3 Animal waste
4 All of these

Humus is
1 Dark coloured amorphous organic matter
2 Further degraded by some microbes and release of organic nutrients.
3 Both 1 and 2
4 Decomposes at an extremely fast rate
Explanation:
Dark coloured amorphous substance called humus that is highly resistant to microbial action and undergoes decomposition at an extremely slow rate

Statement A : Decomposers break down complex organic matter into inorganic substances like carbon dioxide, water and nutrients. Statement B : Detritus is the product resulted due to decomposition.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Statement B is wrong. Dead plant remains such as leaves, bark, flowers and dead remains of animals, including fecal matter, constitute detritus, which is the raw material for decomposition.

Water soluble inorganic nutrients go down into soil horizon and get precipitated as unavailable salts through
1 Humification
2 Leaching
3 Stratification
4 Catabolism
Explanation:
Leaching is a process by which nutrient chemicals or contaminants are dissolved and carried away by water or are moved into lower layers of soil.
