Positive feedback mechanism. A process whereby an initial change in an atmospheric process will tend to either reinforce the process (positive feedback) or weaken the process (negative feedback). See Feedback mechanism.
An example of a feedback mechanism in humans would be the increase in heart rate and respiratory rate which occurs in response to increased exercise or other increased muscle cell activity. Some other examples of feedback mechanisms in living things appear below.he graphic above shows the response of a human to being struck on the knee with a hammer. A change in the environment is called a stimulus. In this situation, the stimulus is the being struck with the hammer. A response is the manner in which the organism reacts to the stimulus.
