Amoeba is a heterotroph i.e they absorb their food directly from the external environment. Some are parasites. Amoeba eat algae, bacteria, plant cells and also protozoans.Amoebas engulf their food.rganisms that are consumers or decomposers are  heterotrophs. A parasite is also a heterotroph. A parasite feeds  off other organisms for its food. An example of a parasite is a  deet tick. An example of a decomposing heterotroph is an earthworm.  An earthworm decomposes biological matter in soil for its food.
Amoeba is a genus of single-celled amoeboid protists in the family Amoebidae.The type species of the genus is Amoeba proteus, a common freshwater organism, widely studied in classrooms and laboratories.moeba proteus has one contractile vacuole which slowly fills with water from the cytoplasm (diastole), then, while fusing with the cell membrane, quickly contracts (systole), releasing water to the outside by exocytosis. This process regulates the amount of water present in the cytoplasm of the amoeba.
