The process of digesting food in an amoeba, being a unicellular organism, is accomplished internally through a simple process called phagocytosis, where the food is engulfed by the cell membrane and broken down by enzymes within the cell. In contrast, digestion in a mouse, a multicellular organism, involves a highly specialized system starting from chewing and swallowing to the production of digestive enzymes in various organs, such as the stomach and pancreas, that break down food into nutrients. Ultimately, the nutrients are absorbed and utilized by various cells and tissues throughout the mouse's body.
