Answer 1

YOUR ANSWER:-

Virus

• A virus is an infectious agent that can only replicate within a host organism. Viruses can infect a variety of living organisms, including bacteria, plants, and animals. Viruses are so small that a microscope is necessary to visualize them, and they have a very simple structure.

Bacteria

• Bacteria, also called germs, are microscopic organisms not visible with the naked eye. Bacteria can live in a variety of environments, from hot water to ice. Some bacteria are good for you, while others can make you sick. Bacteria are single-celled, or simple, organisms.

Protozoa

• Protozoa are small (but not simple) organisms. They are single-celled heterotrophic eukaryotes, which eat bacteria and other food sources.  Many protozoan species are symbionts, some are parasites, and some are predators of soil bacteria and algae.
