The process of maintaining a stable internal environment in an organism is called homeostasis. It involves the regulation of various physiological processes, such as temperature, pH levels, and nutrient balance, to ensure the optimal functioning of the organism. Homeostasis is achieved through feedback mechanisms that respond to changes in the internal or external environment, allowing the organism to adapt and maintain equilibrium. This process is essential for the survival and overall health of the organism.
