Explanation:

Negative feedback is a strategy of the body to maintain homeostasis, that is, to maintain the dynamic balance of the body. It can be defined as a situation where the body causes a negative change, contrary to the factor that is causing the body to become unbalanced. For example:

• when someone's pancreas stops producing the hormone that lowers blood sugar because the person hasn't eaten recently
• when someone's pancreas hormone increases every time they eat, but decreases when they aren't eating
• when a person takes calcium supplements so a gland will stop secreting a hormone that pulls calcium from the bones
