Answer
Enzyme action
Explanation
## Step 1:Physical digestion is all about the mechanical aspects that aid in breaking down food so it can later be used by the body. It uses bodily mechanisms to degrade the food into tinier parts which facilitates easier digestion. Basically, this involves activities like chewing, tearing, grinding which help facilitate degradation of the food.## Step 2:Taking into consideration the answer alternatives i.e., grinding, chewing, enzyme action, tearing, we understand that the first three involve mechanical strategies that facilitate the breakup of food whereas enzyme action involves the role of specific enzymes to catalyze and speed up the breakdown of complex food molecules into simpler ones and are thus associated with 'chemical' digestion.## Step 3:Hence, among the options available, enzyme action is responsibly involved in chemical digestion and not physical digestion.
