Answer

Brief Explanations:

Physical changes in digestion involve altering the form of food without changing its chemical composition. Mashing food with teeth is a mechanical process that only changes the physical state of food (breaking it into smaller pieces). Producing enzymes is a chemical - related process for nutrient absorption. Absorbing nutrients is a physiological process that involves chemical interactions. Salivating to break food into carbohydrates is a chemical change as saliva contains amylase which chemically breaks down starches into sugars.
