Protozoa can be described as?

Explanation:
Protozoa are single-celled eukaryotic organisms. This means they have a nucleus and internal organelles, which sets them apart from bacteria (prokaryotes) and from viruses (which are not cells at all). Protozoa can live on their own in water or soil (free-living) or live as parasites inside other organisms. They are not multicellular organisms, since they are typically microscopic and consist of a single cell. Describing protozoa as having a lifestyle that can be parasitic or free-living best fits their varied nature.
