Positive and Negative Feedback Loop
Organisms also have feedback mechanisms that maintain dynamic homeostasis by allowing them to respond to changes in their internal and external environments. Negative feedback loops maintain optimal internal environments, and positive feedback mechanisms increases the responses. Changes in a biological system’s environment, mainly on the availability of resources, influence responses and activities, and organisms uses different methods to get the nutrients and get rid of wastes. Additionally, the timing and coordination of developmental, physiological and behavioral events are regulated, increasing fitness of individuals and long-term survival of populations
