The statement that the thick fur of a polar bear is an adaptation that allows the bear to live successfully in its environment is true.
The polar bears live in an environment where the temperature is extremely cold as they are found in the polar regions.
In such a cold environment, most of the adaptations of the polar bear are suited to protect it from cold and maintain the body temperature and one such adaptation is the thick fur.
The thick fur traps the air and creates an insulating layer around its body and thus protect it from cold.
