The process of digesting food in an amoeba involves engulfing food particles through phagocytosis, where the cell membrane surrounds the food and forms a food vacuole. The food is then broken down by enzymes within the vacuole and the nutrients are absorbed into the cytoplasm. In contrast, a mouse digests food through the process of ingestion, digestion, absorption, and elimination, starting with chewing and swallowing food and breaking it down further in the stomach with the help of hydrochloric acid and enzymes. The nutrients are then absorbed in the intestines and waste is eliminated through the anus. Overall, both amoebas and mice digest food to extract nutrients for energy and growth, but the process differs in complexity and efficiency due to the organisms' cellular structure and digestive system.
