Correct Answer: C
Explanation:
The earthworm, from the phylum Annelida, has a fairly basic alimentary canal. Food is sucked up by the earthworms mouth, and gets passed through to the earthworms pharynx, or throat. From the pharynx, the food passes through the esophagus, and into the crop, which moistens and stores the food temporarily. Circular and longitudinal muscles propel the food. Once the crop has moistened the food, it moves to the gizzard, which in essence has the same function as the crop, except it actively churns the food inside. The gizzard usually has some grit or gravel in it to assist in this task. From the gizzard, the food enters the intestine, which spans the majority of the worms body.
