Question

Quizplus · Accepted Answer

Ectothermic animals warm themselves primarily through radiation, which involves absorption of heat from the sun's rays. This is why they commonly bask in the sun on warm days. Conduction and convection involve transfer of heat through contact with a heat source or movement of a fluid, respectively, and are less important for ectothermic animals. Evaporation is a cooling mechanism rather than a method of warming.
