What is the role of protozoa?

Protozoa are principally grazers of bacteria, increasing mineralization and making nutrients more available to other organisms; most are aquatic, but they are also widespread animal parasites and symbionts. Their biomass, role in food chains, roles as mutualists and pathogens, and value as biomonitors are reviewed.

What are some helpful protozoa?

Some protozoans are harmful to man because they can cause serious diseases. Others are helpful because they eat harmful bacteria and are food for fish and other animals. There are three different types of protozoa: Ameba, Paramecium, Euglena.
