Detailed explanation-1: -The gizzard is an organ of the digestive system that uses stones swallowed by the earthworm to grind up food and begin the digestion process. The stones within the gizzard function similar to teeth in humans and will break food down into smaller pieces to aid in digestion.

Detailed explanation-2: -The gizzard is a thick muscular organ found in earthworms. It is found in the 8th segment of the earthworm. Gizzard is a part of the digestive system along with the pharynx, the esophagus, the crop, the intestine, etc. Gizzard is formed when the esophagus expands and modifies into a large, distinct, muscular organ.

Detailed explanation-3: -Gizzard. Earthworms do not have teeth, so they use the strong muscles of the gizzard (and grains of sand and soil) to grind up their food.

Detailed explanation-4: -Worms swallow pieces of dirt and decaying leaves, and the food passes through the pharynx, (located in body segments 1-6), the esophagus (segments 6-13), and into the crop, which stores food temporarily. The worm’s stomach is very muscular, so is called a gizzard.

Detailed explanation-5: -They have a structure called gizzard which helps them in grinding their food.
