Negative Feedback Loops. Negative feedback loops are the response of reactions and leads to a decrease in those reactions. Negative loops also maintain homeostasis by creating optimal internal environments. Negative loops are also able to return a system back to target homeostasis. An example of negative feedback loops is blood sugar regulation.
