The process of digesting food in an amoeba is relatively simple as it uses a process called phagocytosis, where it engulfs food particles and digests them within its single cell. In contrast, a mouse has a complex digestive system consisting of various organs like the mouth, stomach, and intestines. Food is broken down by mechanical and chemical processes, absorbed through the walls of the intestine, and transported to various body parts through the circulatory system.
The process of digesting food in an amoeba and a mouse differs based on their cellular nature. In an amoeba, digestion occurs intracellularly within the food vacuole, where enzymes break down complex molecules into simpler forms for absorption by the cell. In contrast, in a mouse, digestion is extracellular and takes place in specialized organs such as the mouth, stomach, and intestines, with enzymes secreted by these organs aiding in the breakdown of food. The digested nutrients are then absorbed by cells lining the mouse's digestive tract.
