Answer:

Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion. The role of chemical digestion is to further degrade the molecular structure of the ingested compounds by digestive enzymes into a form that is absorbable into the bloodstream.
Mechanical digestion uses movement like chewing and the movement of the stomach to break down and digest food, while chemical digestion uses chemicals like stomach acid to break down and digest food.
