Examples of -trophic
One term from biology that features -trophic is heterotrophic, meaning “capable of utilizing only organic materials as a source of food.” It is the adjective form of heterotroph.
The first part of the word, hetero-, means “different, other,” and -trophic, as we’ve seen, concerns what an organism needs for its food. So, heterotrophic has a literal sense of “other-feeding.”
Why? Put simply, heterotrophs, such as animals, require outside sources of nutrition whereas autotrophs, such as plants, can produce their own organic materials from inorganic materials (e.g., carbon dioxide).
In other, etymological words, heterotrophic organisms need “other food” because they can’t make any for themselves.
