Final answer:

Segmentation in the small intestine is a key part of mechanical digestion, while chemical digestion breaks down food molecules into building blocks.


Explanation:

Segmentation is a form of mechanical digestion that occurs mainly in the small intestine. It involves localized contractions of circular muscles in the gastrointestinal tract that isolate sections of the intestine, moving their contents back and forth to mix with digestive juices.

On the other hand, chemical digestion involves breaking down complex food molecules into their chemical building blocks through various digestive secretions. This process starts in the mouth and is completed in the small intestine with the help of enzymes, acids, and salts.
