Answer:
they increase the fertility of soil.
Explanation:
earthworms basically lives inside the soil. they make paths inside to move.. due to which soil becomes porous, air and water could easily enter from the surface to depth of the soil. they bring dead organisms from surface to inside thus increase the fertility.. all they do without any wage. so that's why they are called as farmers friend.
