Organisms that feed on matter not typically considered food
Anextremotroph (from Latinextremus meaning "extreme" and Greektroph (τροφ) meaning "food") is an organism that feeds on matter that is not typically considered to be food to most life on Earth. "Theseanthropocentric definitions that we make ofextremophily and extremotrophy focus on a single environmental extreme but many extremophiles may fall into multiple categories, for example, organisms living inside hot rocks deep under the Earth's surface."[1]
