In an amoeba, the process of digesting food starts with the engulfment of food particles by pseudopodia, forming a food vacuole. Enzymes are then secreted into the vacuole to break down the food into simpler molecules, which are absorbed into the cytoplasm. Waste materials are expelled through exocytosis.
In a mouse, the process of digesting food is more complex. It begins with the mechanical breakdown of food through chewing and mixing with saliva in the mouth, followed by the passage of food through the esophagus into the stomach. In the stomach, gastric acid and enzymes help break down proteins. The partially digested food then moves into the small intestine, where enzymes from the pancreas and the small intestine break down carbohydrates, proteins, and lipids into smaller molecules for absorption. Waste materials are stored in the large intestine and eliminated through the rectum.

The process of digesting food in an amoeba involves engulfment of food particles, secretion of enzymes to break down the food, absorption of nutrients into the cytoplasm, and expulsion of waste materials. In a mouse, digestion begins with mechanical breakdown in the mouth, followed by chemical breakdown in the stomach and small intestine through the action of enzymes. Nutrients are then absorbed into the bloodstream, and waste materials are eliminated through the large intestine and rectum.
