Question

Select the correct statement regarding thermoregulation in animals:

a. Endotherms derive most of their body heat from cellular respiration, while ectotherms derive most of their body heat from the Krebs cycle.

b. Ectotherms do not need to regulate their body temperature, while endotherms do.

c. Ectotherms derive most of their body heat through activity such as movement and shivering, while endotherms derive their body heat from metabolism.

d. Endotherms maintain their body temperature through metabolic heat, while ectotherms must rely on the environment in order to regulate their temperature.

Answer 1

I believe the answer you're looking for is D.

Answer 2

It's D because endotherms are animals that can maintain a constant internal body temperature, regardless of the temperature of their surroundings; ectotherms are animal in which the internal body temperature is the same as the temperature of its surroundings (fish, amphibians, reptiles, etc.).
