Thermoregulation

Play an AI-generated podcast conversation about this lesson

Which type of animal can maintain a stable body temperature in the face of large fluctuations in environmental temperature?

Ectotherms

Neither endotherms nor ectotherms

Endotherms (correct)

Both endotherms and ectotherms

How do ectotherms regulate their body temperature?

By consuming more food

By hibernating during extreme temperatures

By generating heat internally

By seeking out shade or basking in the sun (correct)

Why do ectotherms generally need to consume less food than endotherms?

Because their heat source is largely environmental (correct)

Because they have a larger body size

Because they have a more efficient metabolism

Because they have a higher body temperature
