Answer;
-Negative feedback mechanism
Explanation;
-Negative feedback is a regulatory mechanism in which a 'stimulus' causes an opposite 'output' in order to maintain an ideal level of whatever is being regulated.
-For instance; the maintenance of homeostasis normally involves negative feedback loops. These loops act to oppose the stimulus that triggers them. For example, if your body temperature is too high, a negative feedback loop will act to bring it back down towards the set point, or target value (normal value).
