Final answer:
Homeostasis is the process by which animal organs and organ systems adjust to changes in the environment to maintain a steady state. Acclimatization and physiological adaptation are also processes that enable organisms to temporarily adjust to changes in the environment.
Step-by-step explanation:
Homeostasis is the process by which animal organs and organ systems adjust to internal and external changes in the environment in order to maintain a steady state. This process ensures that body functions are kept within specific ranges even when faced with changes in glucose or calcium levels in blood or external temperatures.
Acclimatization is another process where changes are made in a group of body organ systems to maintain a set point in another system. For example, when an animal migrates to a higher altitude, the body increases the number of red blood cells to adjust to the lower oxygen levels at the new altitude.
Physiological adaptation is also a form of temporarily adjusting to changes in the environment. In this case, living organisms undergo physiological changes that enable them to cope better with existing situations or threats. For instance, the heart beats faster in a threatening situation to provide muscles with more oxygen and enhance performance.
