4. Why are earthworms called farmer's friends in Chapter 9 of Class 7 Science?
Earthworms are known as farmer's friends because they make burrows in soil and by doing so they make the soil porous. This porosity of the soil helps in the respiration of plant roots. The fertility of the soil is also maintained by them. They also help in managing biodiversity. They break organic matter into pieces so that plants can use them. Also, left out castings of earthworms act as fertilizers which farmers use in their farms. As soil becomes porous, the water holding capacity of soil increases.
