What are the differences between prions, viruses, bacteria, archaea, fungi, algal, protists, and parasite worms?

The difference could be found with their definitions. For example, prion is an infectious agent composed of protein material. A virus, on the other hand, is a small infectious agent that replicates only inside the living cells of other organisms. Bacteria are single-celled organisms that grows in diverse environments. The Archaea is a single-celled microorganisms but not like bacteria. A fungus is a eukaryotic organism that includes unicellular microorganisms such as yeasts and molds. Algal is a unicellular or multicellular organisms formerly classified as plants that occurs in fresh or salt water. Protists are a diverse collection of organisms. A parasite worm is an organism that lives on or in a human or another animal and derives its nourishment from its host. Thank you for posting your question.
