right said geometry hater !
they consume the nutrients of the soil.
What worms eat depends in part on where they live. Worms can live closer to the surface or much deeper underground. On the surface, worms eat a variety of organic materials, such as dead grass and leaves that have fallen from the trees. There are microscopic organisms that live on these leaves. These organisms provide the worm with a variety of algae, fungi and bacteria that are essential for the worm’s diet.

Worms that live deeper under the ground have a diet that is primarily raw dirt. The worms eat the bacteria, fungi and algae that are in the dirt. The dirt passes through the worm and comes out in what is known as worm casts. This is a nice way of saying excrement.
