- Negative feedback occurs when conditions change from the ideal or set point and returns conditions to this set point
- It works in the following way:
- if the level of something rises, control systems are switched on to reduce it again
- if the level of something falls, control systems are switched on to raise it again
- Negative feedback mechanisms are usually a continuous cycle of bringing levels down and then bringing them back up so that overall, they stay within a narrow range of what is considered ānormalā
