Detailed explanation-1: -Feedback loops are important because they allow living organisms to maintain homeostasis. Homeostasis is the mechanism that enables us to keep our internal environment relatively constant – not too hot, or too cold, not too hungry or tired.

Detailed explanation-2: -Maintenance of homeostasis usually involves negative feedback loops. These loops act to oppose the stimulus, or cue, that triggers them. For example, if your body temperature is too high, a negative feedback loop will act to bring it back down towards the set point, or target value, of 98.6 ∘ F

Detailed explanation-3: -Feedback loops are processes where designers use a system’s outputs as inputs to find cause-and-effect relationships within it. Some systems (e.g., the environment) have many feedback loops, and the effects of human actions can take decades to show. In complex systems, feedback loops can hide causal links and problems.

Detailed explanation-4: -In climate change, a feedback loop is something that speeds up or slows down a warming trend. A positive feedback accelerates a temperature rise, whereas a negative feedback slows it down.
