Which mechanism explains how an ectotherm, such as a lizard, maintains its body temperature in a desert environment?

💡 Explanation

Ectotherms rely on external sources for thermoregulation because they lack significant internal heat production. Behavioral thermoregulation, like basking in the sun, allows lizards to absorb heat, therefore it regulates their body temperature, rather than using metabolic processes like brown adipose tissue.
