What is the difference between negative feedback and positive feedback mechanisms? Negative feedback mechanisms return a system to a set point; positive feedback mechanisms amplify a response. Negative feedback mechanisms move a system away from a set point; positive feedback mechanisms stabilize a system at a set point. Negative feedback mechanisms stabilize a system at a set point; positive feedback mechanisms change the set point.

Feedback mechanism

Explanation:

Negative feedback mechanisms return a system to a set point; positive feedback mechanisms amplify a response

Positive feedback mechanism

A positive feedback mechanism occurs in nature when the product of a reaction leads to an increase in that reactionIf one looks at a system in homeostasis, a positive feedback mechanism moves a system further away from the target of equilibrium and does this by amplifying the effects of a product or event and occurs when something needs to happen quickly

Negative feedback mechanism

A negative feedback mechanism occurs in biology when the product of a reaction leads to a decrease in that reactionIn this way, a negative feedback mechanism brings a system closer to a target of stability or homeostasis.Negative feedback mechanism helps in the maintenance of a steady, stable state
