Detailed explanation-1: -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.

Detailed explanation-2: -This is the process where complex molecules like proteins, fats, and carbohydrates are broken down into smaller pieces that your body can use. It requires special proteins called enzymes.

Detailed explanation-3: -The type of chemical reaction that occurs during digestion is decomposition and exothermic reaction.
