Quizplus · Accepted Answer

The correct term for a stimulus that resets the circadian rhythm is zeitgeber, which is a German word meaning "time giver." It refers to an environmental cue or signal, such as light or temperature, that helps to synchronize an organism's internal biological clock with the external day-night cycle. Lichtgeber is a similar term that specifically refers to light as a zeitgeber. Zeitadian and circazeit are not valid terms.
