Question

Earthworm helps farmers by

• A. Destroying harmful bacteria
• B. Destroying harmful insects
• C. Making soil porous and loose
• D. Both A and B

Answer 1

The correct option is C Making soil porous and loose

Pheretima posthuma is known as the 'friends of farmers' as they make burrows in soil and make it porous which helps in respiration and penetration of the developing plant roots. The process of increasing soil fertility by the worms is known as vermicomposting. Earthworm feed on the organic debris present in the soil. Thus helping the farmers to increase the yield of the crop.

So the correct answer is 'Making soil porous and loose'.
