Detailed explanation-1: -It occurs when the original effect of the stimulus is reduced by the output. Negative feedback mechanism normalizes the things when they start becoming too extreme. For eg., the thyroid gland is regulated by a negative feedback mechanism.
Detailed explanation-2: -Most hormones are controlled by negative feedback, in which the hormone feeds back to decrease its own production. This type of feedback brings things back to normal whenever they start to become too extreme. Positive feedback is much less common because it causes conditions to become increasingly extreme.
Detailed explanation-3: -In negative feedback, rising levels of hormones feedback to the hypothalamus and pituitary gland to decrease the production of the hormones. In positive feedback, rising levels of hormones feedback to increase hormone production.
