Protozoa also protozoan , plural protozoans is an informal term for a group of single-celled eukaryotes , either free-living or parasitic , which feed on organic matter such as other microorganisms or organic tissues and debris. In some systems of biological classification , Protozoa remains a high-level taxonomic group.

It is found in fresh water ponds, pools, streams, lakes, rivers etc. It is found in abundance in stagnant water bodies containing dead and decaying organic matter.
Protozoans may take food into the cell at a specific point, such as the cytostome a well-developed feeding groove , at a particular region of the cell surface, or at any random point of entry. In the collared flagellates , or choanoflagellates, for example, the collar and flagellum operate in feeding. The collar, composed of fine pseudopodia , surrounds the flagellum. The beating flagellum creates a water current, causing water to move through the collar. Particles of food in the current are trapped on the collar and are ingested by pseudopodia at its base.
