Detailed explanation-1: -A crop is a thin-walled expanded portion of the alimentary tract used for the storage of food prior to digestion that is found in many animals, including gastropods, earthworms, leeches, insects, and birds.

Detailed explanation-2: -A crop (sometimes called a croup or craw) is a thin-walled expanded portion of the alimentary canal used for storing food before digestion. It is found in many animals. It occurs in birds, some dinosaurs, and invertebrate animals such as gastropods (snails and slugs), earthworms, leeches, and insects.

Detailed explanation-3: -Birds. In a bird’s digestive system, the crop is an expanded, muscular pouch near the gullet or throat. It is a part of the digestive tract, essentially an enlarged part of the esophagus. As with most other organisms that have a crop, it is used to temporarily store food.

Detailed explanation-4: -When the earthworm swallows small particles of soil and bits of dead plants and animals, muscles push the food to a chamber or sac called a crop. The crop stores food for a short time.

Detailed explanation-5: -The digestive tract includes the oral cavity and associated organs (lips, teeth, tongue, and salivary glands), the esophagus, the forestomachs (reticulum, rumen, omasum) of ruminants and the true stomach in all species, the small intestine, the liver, the exocrine pancreas, the large intestine, and the rectum and anus.
