NTR: microorganism

[ramonawalls]

I think CARO is the right place for this term. We need it to define microbial community in PCO - PopulationAndCommunityOntology/pco#22. May first need to add a class to PATO for microscopic.

Proposed definition (adapted from https://en.wikipedia.org/wiki/Microorganism):

A microscopic organism, virus, or viroid. Microorganisms include all bacteria, archaea, viruses and viroid, and almost all protozoa, as well as some fungi, algae, and some animals, such as rotifers. Many macroscopic animals and plants have microscopic juvenile stages.

If it feels like domain creep, perhaps a new home would be useful: PopulationAndCommunityOntology/pco#22 (comment)

(sorry to complicate this, but it may be worth it in the mid- to long-term; if CARO can host it temporarily, that would be great to allow things to move)

On further thought, I am beginning to think maybe PCO should host these polyphyletic groups of organisms (e.g., microorganism, herp, bryophyte). There are lots of them, and they are probably spread out over various taxon specific ontologies at this point. As the terms will often be used to collections of organisms, PCO may be a good place for them. Any thought on this @cmungall or @dosumis?
