What is negative loop?

A negative loop, often referred to in systems theory or feedback systems, is a process where the output of a system feeds back into the system in a way that reduces or counteracts the initial input or stimulus. This mechanism helps to maintain stability and promote equilibrium by diminishing fluctuations. In biological systems, for example, negative feedback loops are crucial for regulating processes like hormone levels and body temperature. Overall, they play a vital role in maintaining homeostasis in various systems.
