Question

Why are earthworms, spiders, snakes etc., called friends of farmers?

Answer 1

Earthworms decompose the plant and animal matter and help in increasing the soil fertility. Earthworms also loosen soil by burrowing deep into the soil which helps in easy root penetration into the soil. Spiders eat many small insects which feed on crops thereby protecting the crop from insects. Snakes eat rats and mice which damage crops. All together these are eco- friendly by which chemical usage can be decreased.
