Answer Details
The breaking down of food in the alimentary canal is called digestion. Digestion is the process of breaking down food into simpler substances that can be absorbed and used by the body. It involves both mechanical and chemical processes. The mechanical process involves the physical breakdown of food into smaller pieces, which increases the surface area for chemical digestion. Chemical digestion, on the other hand, involves the breakdown of large molecules such as proteins, carbohydrates and fats into smaller molecules such as amino acids, glucose, and fatty acids. These smaller molecules can be absorbed into the bloodstream and transported to the cells for energy and other functions. Therefore, the correct answer is "digestion".
