What is homeostasis? which characteristic of life is it a part of?

Homeostasis is any self-regulating process by which an organism tends to maintain stability while adjusting to conditions that are best for its survival. If homeostasis is successful, life continues; if it’s unsuccessful, it results in a disaster or death of the organism. The “stability” that the organism reaches is rarely around an exact point (such as the idealized human body temperature of 37 °C [98.6 °F]). Stability takes place as part of a dynamic equilibrium, which can be thought of as a cloud of values within a tight range in which continuous change occurs. The result is that relatively uniform conditions prevail.

The process of maintaining a balance of internal environment in response to changes. When conditions in the body are too high or too low, it adjusts. All organ systems work together to maintain homeostasis. Failure to maintain results in disease or death.
