Digestion
Digestion is the mechanical and chemical breaking down of food into smaller components, such as into a form that can be absorbed, for example, into a blood stream. Digestion is a form of catabolism, which is a break down of macro food molecules to even smaller ones.
Different organisms use different mechanisms to digest the food they eat.
