Why “chemoautotrophic” is a great word

Obtaining energy and synthesizing organic compounds from the oxidation of inorganic chemical substances, independent of light. Formed within English by compounding; etymons: chemo- (combining form from 'chemistry' or 'chemical') + autotrophic (from auto- 'self' + -trophic 'nourishing'), first attested in 1945. Unlike photoautotrophic, which harvests sunlight, or heterotrophic, which consumes other life, chemoautotrophic describes a primal, solitary alchemy. It is the bacterial bloom in the absolute dark of a hydrothermal vent, metabolizing sulfur; the unseen conversion of ammonia to nitrite in barren soil; the foundational rusting of iron deep within a rock—a life that builds itself from stone and chemical fire, whispering of origins in a world before the sun.
