Which statement is not true of endothermic animals?
a. they are considered "warm blooded".
b. humans and other mammals are endothermic.
c. they regulate body temperature through behavioral mechanisms--moving into the sun or shade as needed.
d. they regulate their body temperature by physiological mechanisms--shivering, sweat, etc.

Hello! Your answer would be C, They regulate body temperature through behavioral mechanisms.

An endothermic animal is one which is capable of maintaining its own body temperature. They do this through physiological mechanisms, which is what the last choice is saying - these involve things such as hormones, sweating, etc.

These endothermic animals are considered warm blooded. This is because they can make their own body heat. Humans and other mammals are endothermic. We generate our own heat - we don't rely on sunbathing or shade to cool down or heat up our internal body temperature.

Hope this helps!
