heterotrophic

The word 'heterotrophic' is a modern scientific coinage built from classical Greek roots to describe a fundamental biological mode of nutrition. The first element, 'hetero-', originates from the Greek heteros, meaning "the other (of two), different", which itself derives from the Proto-Indo-European root sem- meaning "one" and -tero-, a contrastive suffix. The core component '-troph-' comes from the Greek trophē ("nourishment, food"), related to trephein ("to make solid, nourish, rear"). Combined, 'heterotroph' literally means "other-nourished", logically describing organisms that must consume different, pre-formed organic matter for sustenance, as opposed to producing their own. The adjectival suffix '-ic', of Latin and Greek origin, was then appended to form the term used in biological classification.
