Which limitation arises when atmospheric carbon dioxide levels exceed the buffering capacity of avian air sacs?

💡 Explanation

When CO2 exceeds the air sacs' buffering, the Bohr effect decreases hemoglobin's oxygen affinity because increased acidity hinders oxygen binding, resulting in reduced O2 uptake efficiency. Therefore decreased oxygen uptake results, rather than soaring limitations, thermal issues, or infection susceptibility, which depend entirely on other factors.
