27.1 What Do I Know About the Human Body, So Far?

Humans are endotherms, which means they generate heat from within their bodies. Other chordates, such as reptiles, control their body temperature by behavior—these are extotherms. Endotherms eat much more food and use much more oxygen than ectotherms with the same body mass.

Working with a partner, answer the following question: Why do you think endotherms must eat more food and use more oxygen than ectotherms of the same body mass?
