This positive feedback loop continues until the baby is born. Homeostasis is order. If the pH of their body or their environment fluctuates too much the organism can die. Why is the water cycle important to the environment? For instance, the stomach maintains a pH that's different from that of surrounding organs, and each individual cell maintains ion concentrations different from those of the surrounding fluid.
