1. (biology, rare) Relating to an individual organism.Examples: "The complete and accurate repetition of phyletic by biontic development is obliterated and abbreviated by secondary contraction, as ontogeny strikes out for itself an ever straighter course; accordingly, the repetition is the more complete the longer the series of young stages successively passed through."; "There is no need to clutter the literature with more long Germanic compounds: suffice it to say that referring to the organism/habitat relationship as biontic, philic or xenic summarises the above arguments succinctly."

2. (obsolete or nonstandard) Biological.
