WebIf heat generation exceeds the heat loss, mechanisms such as panting or perspiring increase heat loss. Unlike ectotherms, endotherms can be active and survive at quite low external temperatures, but because they must produce heat continuously, they require high quantities of “fuel” (i.e., food).
