Answer:
A on edge
Explanation:
Homeostasis is needed for an organism to survive because it keeps its internal environment stable.
It ensures that important physiological factors such as temperature, pH and nutritional levels remain within ideal limits. The stable environment allows for the proper functioning of cells and tissues, supporting metabolism as well as the creation of energy and enzyme activity.
Homeostasis enables organisms to adjust to changes in the external environment, by coordinating responses including temperature control, fluid balance, and hormone release. Many organ systems must work together to keep the body balanced. Without homeostasis, cellular processes would be disturbed and the organism's ability to adjust to environmental changes would be compromised, jeopardizing its ability to survive.
