Biology - Organisms and Populations Question with Solution | TestHub

Conformers are organisms that cannot maintain a constant internal environment. Their body temperature changes with the ambient temperature, and in aquatic animals, the osmotic concentration of the body fluids changes with that of the ambient water osmotic concentration.

Regulators are organisms that maintain a constant internal environment (homeostasis) despite changes in the external environment.

Organisms that move away from stressful conditions are called migrators, while those that suspend their activities undergo processes like hibernation, aestivation, or diapause.

Answer: whose body temperature and osmotic concentration changes with that of surrounding.
