Question

how do earth worms help the soil​

Answer 1

Answer:

Earthworms | NRCS Soils - Natural Resources Conservation Service Earthworms need the food and habitat provided by surface residue, and they eat the fungi that become more common in no-till soils. As earthworm populations increase, they pull more and more residue into their burrows, helping to mix organic matter into the soil, improving soil structure and water infiltration.
