Can you tell me the difference between a bacterium, a virus, a fungus and a parasite?

Bacteria are single-celled organisms that can be either prokaryotic or eukaryotic. They are typically found in soil, water, and air. Viruses are smaller than bacteria and are made up of genetic material surrounded by a protein coat. Fungi are multicellular organisms that include mushrooms and molds. Parasites are living organisms that live off other organisms for food, shelter, and reproduction.
