In an amoeba, the process of digesting food occurs internally within its single cell through phagocytosis, where the cell engulfs food particles and breaks them down through enzymes. In a mouse, digestion occurs in a specialized digestive system that includes organs such as the stomach, intestines, and liver, where food is broken down into nutrients that are absorbed and utilized by the body. Both organisms ultimately rely on the breakdown of food for energy and growth, but the mechanisms and complexity of digestion differ due to their unicellular and multicellular nature.
