Final answer:
Homeostasis in living things refers to the maintenance of a stable, internal environment. Organisms regulate their internal conditions to ensure optimal functioning.
Step-by-step explanation:
Homeostasis in the context of living things refers to the maintenance of a stable, internal environment. It is the process by which organisms regulate their internal conditions, such as body temperature, pH levels, and glucose concentration, within a narrow range to ensure optimal functioning.
For example, in humans, when the body temperature rises due to physical activity or external factors, homeostasis mechanisms such as sweating and vasodilation are activated to cool the body down and restore the ideal temperature.
Homeostasis involves a series of feedback loops, where sensors detect changes in the internal environment and send signals to effectors, which then respond to restore the balance.
