Does the digestive system in earthworms show specialization of parts?

Yes, the digestive system of earthworms shows specialization of parts. It is divided into distinct regions, including the mouth, pharynx, esophagus, crop, gizzard, and intestine, each with specific functions in the digestion and processing of food. This specialization allows for efficient breakdown and absorption of nutrients as the earthworm consumes organic matter from the soil.
