Temporary storage occurs in the crop of an earthworm
The crop is part of the stomach and digestive system of an earthworm. We (my class and I) just did the dissection of an earthworm awhile ago, and basically it is the regular stomach.
The digestive system is partitioned into many regions, each with a certain function. The digestive system consists of the pharynx, the esophagus, the crop, the intestine and the gizzard. Food such as soil enters the earthworm's mouth where it is swallowed by the pharynx. Then the soil passes through the esophagus, which has calciferous glands that release calcium carbonate to rid the earthworm's body of excess calcium. After it passes through the esophagus, the food moves into the crop where it is stored and then eventually moves into the gizzard. The gizzard uses stones that the earthworm eats to grind the food completely. The food moves into the intestines as gland cells in the intestine release fluids to aid in the digestive process. The intestinal wall contains blood vessels where the digested food is absorbed and transported to the rest of the body.
The earthworm's crop and gizzard feel different because they perform two different functions. The gizzard is hard to the touch because it is used to grind the soil the earthworm takes into its body. The crop is soft and more saclike because it stores food that the earthworm separates from the other things it takes in.
Earthworms break down substances by means of a crop which is situated below the gullet. The crop is lined with a very hard skin and the grit in the crop, together with digestive juices crushes the sand and other decayed vegetable matter into a paste.

gizzard where it is digested
Yes. It has a mouth, crop, a gizzzard , intestines and an anus.
the crop
The crop in an earthworm stores food temporarily before it moves on to the gizzard for further digestion. The crop is a pouch-like structure located in the earthworm's digestive system where food is stored.

In a cross section anterior to the gizzard of an earthworm, you would find the crop, esophagus, pharynx, and the mouth. The crop stores food temporarily before it moves to the gizzard for further mechanical digestion.
Yes, the esophagus of an earthworm lies beneath the pharynx. The esophagus is the part of the digestive system that connects the pharynx to the crop, where the initial stages of digestion take place in an earthworm.
The crop serves an important role in the earthworm digestive system. Food is stored here until it can move into the gizzard.
