While writing the word "antibiotic" I stopped and looked at it...that word, for a moment. And of course back in grade school science class we were taught the word biotic refers to life forms or all things pertaining to life.
Just to make sure that hadn't changed, I checked wikipedia:
"Biotic means relating to, produced by, or caused by living organisms. Biotic is a living component of a community; for example organisms, such as plants and animals. Biotic may also refer to: Life, the condition of living organisms."
Yep, that's about as simple as it gets.
