Living systems must maintain their chemical and physical organizations in order to prevent death. how do living organisms maintain the organization of their internal systems?

living organism maintain the organization of their internal system using homeostasis.

Explanation: In biology, homeostasis is the state of steady internal physical and chemical conditions kept by living systems. This dynamic state of equilibrium is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range). Other variables include the pH of extracellular fluid, the concentrations of sodium, potassium and calcium ions, as well as that of the blood sugar level, and these need to be regulated despite changes in the environment, diet, or level of activity. Each of these variables is controlled by one or more regulators or homeostatic mechanisms, which together maintain life.
