How do Earthworm ingesting?

Earthworms ingest food through their mouths, where they consume organic matter, soil, and decaying plant material. As they burrow through the soil, they take in these materials, which are then ground up by their muscular gizzard. Nutrients are absorbed in the intestine, and any indigestible remnants are expelled as castings. This process plays a vital role in soil aeration and nutrient cycling.
