The worms do make holes but it is to but oxygen in to decompose the soil and therefore making compost, they also drag leafs into the compost to eat and to make more soil well theirs your answer :).
An earthworm, while moving, chews up some soil and spits out the same amount of soil back into the ground. The soil which was eaten becomes fertile and more plants will grow on fertile soil. therefore, an earthworm helps a farmer by making soil fertile.

Omg,like i seriously like do not know but anyway let me make an educated guessFertile soil is when the soil is not rich in nutrients .The oppsite of fertile soil is fertilizated soil.Hope i helped!
birds depend on the worms for food. also other organisms living in the soil depend on it because they leave holes in the soil and make it fertile an the holes need to be there so water and air can travel down there. without worms the organisms wouldnt be able to breathe or drink
