The source from which food or nutrients are acquired.


Deriving from the Greek -trophikós, which means "pertaining to food or nourishment," the suffix -troph relates to an organism's food source.

autotroph: an organism that makes its own food (from "auto-", meaning "self")

heterotroph: an organism that gets its nourishment from other sources ("hetero-" means "different")

embryotroph: nutritional material which is supplied to the embryo itself during development
