compare the process of digesting food in an amoeba (unicellular) to those in a mouse (multicellular),

In both an amoeba and a mouse, the process of digesting food begins with the ingestion of food particles. In an amoeba, the food particles are engulfed by the cell membrane and are then broken down by enzymes within the cell. The nutrients are then absorbed into the cell and used for energy. In a mouse, the food particles are first broken down by the teeth and then swallowed. The food then travels through the esophagus and enters the stomach, where it is further broken down by enzymes and acids. The nutrients are then absorbed into the small intestine and used for energy.
Since mice are unicellular, all digestion must take place within the one cell. This includes taking in food, absorbing energy, and defecation. Amoeba, on the other hand, have many cells so cells will specialize to do different jobs for the body. Organs such as the mouth, small intestine, and anus drive the process of digestion in amoebas.
