What is the purpose of worms?
By their activity in the soil, earthworms offer many benefits: increased nutrient availability, better drainage, and a more stable soil structure, all of which help improve farm productivity. Worms feed on plant debris (dead roots, leaves, grasses, manure) and soil.
Do worms feel pain?

Do we need worms to live?
Earthworms are like free farm help. They help to "turn" the soil—bringing down organic matter from the top and mixing it with the soil below. Another interesting job that the worm has is that of making fertilizer. If there are 500,000 worms living in an acre of soil, they could make 50 tons of castings.
What if all worms died?
Because earthworms eat dead plants, they are called decomposers. If earthworms disappeared, all the dead plants would just pile up on the ground. Luckily, earthworms are hungry animals and can eat their own bodyweight each day. Plants need nutrients to grow.

People have more in common with deep-sea worms than one might suspect. Over 500 million years ago, humans and certain worms shared a common ancestor, and people still share thousands of genes with the worms, said scientists who recently sequenced genomes from two marine worm species.
Why do worms have 2 hearts?
Earthworm possess 5 pairs heart. Earthworms do not have a genuine heart because they are worms, but they do have aortic arches, which connect ventral and dorsal veins and pump blood. An earthworm is a terrestrial invertebrate, which means it doesn't have a heart and has an open circulatory system.
