Which benefit results when a bird regulates air flow through its air sac system?

💡 Explanation

Birds use their air sacs to facilitate evaporative cooling through the respiratory tract via convective heat loss, rather than by panting. This is because unidirectional flow maximizes efficiency, therefore the bird requires less energy for thermoregulation rather than by alternative cooling methods used to regulate breathing.
