Explain why the earthworm is considered a friend of the farmer.

(N/A) Earthworms are known as 'friends of farmers' because they burrow into the soil,making it porous. This porosity facilitates soil aeration and allows for easier penetration of developing plant roots. The process of increasing soil fertility through the action of earthworms is known as vermicomposting. Additionally,they are widely used as bait in game fishing.
