Given below are two statements. In the light of the above statements, choose the most appropriate answer from the options given below.

Statement I:Composting is the aerobic degradation of organic materials by microorganisms, mainly under controlled conditions.

Statement II:Both macro-organisms and micro-organisms play an important role in the composting process.

ABoth Statement I and Statement II are correct ✓ Correct

BBoth Statement I and Statement II are incorrect

CStatement I is correct but Statement II is incorrect

DStatement I is incorrect but Statement II is correct

Correct answer: (A) Both Statement I and Statement II are correct

Explanation

Composting turns organic waste into humus through controlled aerobic microbial action.

Statement 1 is correct because oxygen-using microorganisms break down the material under managed conditions.

These conditions include steady moisture, aeration and a balanced carbon to nitrogen ratio.

Statement 2 is correct because both macro-organisms and micro-organisms take part in the process.

Earthworms, insects and mites shred the matter while bacteria and fungi decompose it.

Aerobic composting mostly gives off carbon dioxide, water and heat rather than methane.
