Final answer:
Homeostasis aids in the survival of an organism by regulating body temperature through thermoregulation and having adaptations for withstanding extreme temperatures.
Step-by-step explanation:
Homeostasis is the process by which organisms maintain internal conditions within a narrow range almost constantly, despite changes in the environment. One way homeostasis aids in the survival of an organism is by regulating body temperature through thermoregulation. Organisms have adaptations, such as fur, feathers, blubber, or sweating, that help them withstand extreme temperatures and either conserve or shed excess body heat in order to maintain a constant temperature.
