What would be an advantage for an animal that conforms to a changing environmental condition, such as temperature?
a) the animal's internal temperature would remain constant, even though the external temperature had changed.
b) the animal's internal temperature would change opposite to the change in the external temperature.
c)the animal would spend less energy regulating its internal temperature.
d) the animal would spend more time looking for food.

C)The animal would spend less energy regulating its internal temperature.

Explanation:

Conformers are the organisms that do not maintain the constant internal body conditions. For instance, their body temperature and osmotic concentration of body fluid change with the changes in the surroundings. To maintain constant internal body conditions, regulators spend lots of metabolic energy.

Therefore, regulation of body conditions within a narrow range become energetically very expensive process for organisms. This is apparent for organisms with a small body size that tend to lose heat rapidly to the surroundings under cold temperature conditions. Therefore, conformers spend less energy than regulators to maintain internal body conditions such as temperature.
