Define "worm". If you mean earthworms, which are in Phylum Annelida, then the answer is a resounding "yes!". Earthworms decompose organic matter by eating decaying plants, and their feces (called "castings" in polite earthworm circles) is one of the best fertilizers in the world.
Earthworms also improve the soil by their digging and tunneling. Their movement turns over the soil, mixing nutrients . Their tunnels help water soak in and air get in too.
Other kinds of worms are not so good. Certain nematodes, which are smooth and frequently microscopic, can damage the roots of plants. Farmers spend lots of money trying to control this type of worm.
While earthworms are usually beneficial in that they help break down organic matter allowing nutrient cycling, too many earthworms can actually result in the loss of the grass in a lawn. Excess worm castings coupled with excessive moisture can lead to the loss of grass. I have been witnessing his with the lawn that I planted two years ago. Each rainy season, portions of the lawn with large numbers of earthworms become essentially covered in mud due to the amount of worm castings, slowly causing my grass to disappear. I have reseeded these areas (both side yards), successfully, only to have the grass slowly disappear during the next rainy season - and it is not related to the drainage. There are things you can do to reduce the number of earthworms.
If all the earthworms disappeared from a lawn, more earthworms would come in. But, if your question is that what would happen if earthworms would no longer live in a lawn, then the lawn would become less fertile, because earthworms keep the soil good.
I would not be concerned as the garter snake is quite harmless and is probably feeding on earthworms in your lawn.
Earthworms are generally solitary. large groups of earthworms usually congregate because of good soil conditions, not because of other worms. Earthworms are generally solitary. large groups of earthworms usually congregate because of good soil conditions, not because of other worms.
Because earthworms eat just about every other organism in the soil.
worms are good for soil because they weather rocks
Worms are good for crops.

They are good at digging holes so more water and air can come through.
