Well, the amoeba is a very complicated type of cell life form. An Amoeba does not go through a well planned diet, so they get much larger then other cells. Amoeba's basically eat anything they can find or die trying.
An amoeba ingests large food particles by a process called phagocytosis. During phagocytosis, the amoeba uses pseudopods to surround the food particle and form a food vacuole, which contains the ingested material. The food vacuole then fuses with lysosomes to digest the food.
