Positive & Negative Feedback in Biological Systems

WebThere are two main types of feedback mechanisms in biology: positive feedback and negative feedback. A negative feedback mechanism is when a living system works to counteract a stimulus to return the system back to homeostasis. Positive feedback occurs when a living system amplifies a stimulus to move the body away from steady state.
