Answer

Positive feedback mechanisms amplify the effects of an initial change in the system, leading to a self-reinforcing loop that pushes the system further away from its original state. It enhances the original deviation, promoting more significant changes and tends to destabilize the system. On the other hand, negative feedback mechanisms work to counteract the effects of an initial change and bring the system back to its original state. It reduces the original deviation, stabilizing the system, and acts as a regulatory mechanism.
