Detailed explanation-1: -A negative feedback is a self-regulatory system in which it feeds back to the input a part of a system’s output so as to reverse the direction of change of the output. The process reduces the output of a system in order to stabilize or re-establish internal equilibrium.

Detailed explanation-2: -Positive vs. Negative Feedback The key difference between positive and negative feedback is their response to change: positive feedback amplifies change while negative feedback reduces change.

Detailed explanation-3: -Another example of negative feedback is the regulation of the blood calcium level. The parathyroid glands secrete parathyroid hormone, which regulates the level of calcium in the blood. If calcium decreases, the parathyroid glands sense the decrease and secrete more parathyroid hormone.
