Amoebas are unicellular organisms that engulf their food through a process called phagocytosis. They bring in food into their cell through their pseudopodia, which surrounds the food particle, encases it in a vesicle, and breaks it down with enzymes. Mice, on the other hand, are multicellular organisms with a digestive system composed of specialized organs such as the mouth, stomach, and intestines. The digestive system in mice breaks down food chemically and mechanically via enzymes and muscular contractions.
