definition of "organic" that fit the usage in question was
"forming an integral element of a whole." The definition for
"inorganic" did not refer in any way to parts or wholes. It only
referred to living or dead, specifically, "being composed of matter
other than plant or animal." Nonorganic, however, is conveniently
defined only as "not organic," making it the better candidate.
