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.
An amoeba is a type of unicellular organism usually found in water around decaying vegetation, in wet soil and in animals such as humans.It is relatively advanced, and can extend and retract blob-like arms called pseudopodia, which it can use to grasp food particles and to propel itself through microscopic terrain.moebas use arms called pseudopods to acquire food. The transparency of most amoebas makes them ideal subjects for microscopic study. It is believed that amoeba were first viewed under a microscope in the mid-1700s. The protists are a group of life forms that are neither plant nor animal.
