Why do endotherms need more food than ectotherms?

WebJun 20, 2011 · Evaporative cooling can only occur when the surface temperature of the endotherm is higher than the environmental wet-bulb temperature, and evaporative heat loss is severely curtailed at high humidities. To adapt to more humid and hotter environments, endotherms would need to increase their T b to maintain a negative T b –T a gradient.
