Which outcome occurs when a bird's air sacs experience fungal infection affecting oxygen absorption efficiency?

💡 Explanation

When a bird's air sacs are infected, gas exchange is inhibited because the fungal infection impairs the respiratory surface area, leading to reduced oxygen uptake. Therefore, decreased flight at high altitudes results, rather than insulation, balance, or vocalization, which depend on different body systems and mechanics.
