WebSep 16, 2024 · Contractions at childbirth and fruit ripening are examples of positive feedback. A negative feedback loop happens to lessen the change. The response effect is attenuated to restore the system to a stable state. Negative feedback happens to minimize the change or output. 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.
