What is negative feedback and positive feedback in homeostasis
Answers
Explanation:
Homeostasis is maintained by negative feedback loops within the organism. In contrast, positive feedback loops push the organism further out of homeostasis, but may be necessary for life to occur. Homeostasis is controlled by the nervous and endocrine systems in mammals.
Answer:
Feedback is an event that occurs when the output of a system is used as input back into the system as part of a chain of cause and effect. This alters variables in the system, therefore resulting in different output and consequently different feedback as well, which can either be good or bad. In the case of a system which requires knowledge of the output in order to improve or deliver on a specific output, then feedback is essential and good. But for a system that does not require feedback, such as an audio system, then feedback is often bad. Take for example a microphone and speaker system, when the sound from the speakers (output) is picked up by the microphone (input) it creates a negative feedback that produces a very high pitched sound.
