How are endothermic and ecothermic different?

Answer 1

Ectotherms, such as reptiles, rely on their external environment for temperature. Their body temperatures fluctuate with changing conditions. They do however have mechanisms to change their temperature, such as sitting in the sun or reducing physical activity.

The older term for ectotherms is 'cold blooded' - however, this is not commonly used anymore because often ectotherms can have body temperatures much higher than endotherms.

Endotherms, such as humans, have internal control mechanisms for body temperature. This means that despite changes in environmental temperature, their body temperatures are maintained within a narrow range.

Answer 2

Endothermic animals regulate their body temperature internally, using metabolic processes to generate heat. Ectothermic animals rely on external sources of heat, such as the sun, to regulate their body temperature.

Answer 3

people should already have this answer. scientist should have done it.
