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.
Amoebas are single-celled organisms. The so-called brain-eating amoeba is a species discovered in 1965 and formally named Naegleria fowleri. Although first identified in Australia, this amoeba is believed to have evolved in the United States. There are several species of naegleria, but only the N. fowleri species causes human disease. Like other amoebas, naegleria reproduce by cell division. When conditions are less than optimal, amoebas become inactive cysts. When conditions are favorable, the cysts turn into trophozoites -- their feeding form.
