      Okay, here’s a dumbed down version for you,

      Bacteria – unicellular organisms which produce toxins as they grow and divide

      Virus – protien shells packed with genetic information – which are considerably smaller than a cell. It can’t reproduce outside the cell unlike bacteria, so they invade the cells and inject the genes into the nucleus and creates copies of itself

      Fungi – causes disease by absorbing nutrients, and producing toxins

      By the way, what do you mean by parasites? Pathogenic bacteria, and fungi are all parasitic in nature, if I’m not wrong.

      Genotype: I would guess it’s something like nematodes or tapeworms. On the other hand, for sure are not all bacteria and fungi pathogenic!Think about bacteria in your gut and Bifidus actiregularis 😆 😆

      Parasite is an organism that lives inside (endo-) or outside (ectoparasite) some other organism and this relationship is good for the parasite and bad for the host. The difference between a predator and a parasite is that the parasites’ host usually doesn’t die. So I guess it can be any kind of organism – plant, animal, bacteria… :-).

      yes, of course, but in the context of tracey’s question, I would suggest the multicellular organisms

      quote JackBean:

      Where did I say that? I said most of the pathogenic bacteria/fungi are parasitic in nature 🙄
