The Brainliest Answer!
Chemical digestion refers the to the breakdown of food in the mouth, stomach and intestines through the use of acids and enzymes. Mechanical digestion processes--such as chewing, swallowing and the muscular movements that move food through the digestive tract--support chemical digestion by physically breaking whole foods into smaller pieces to facilitate chemical breakdown.
