Which outcome impedes bird ascension when air sacs rupture?

💡 Explanation

Ruptured air sacs reduce pulmonary function, and therefore inhibit pressure regulation. Decreased buoyancy results because the bird struggles to maintain altitude rather than climbing. Other options would affect metabolism or aerodynamics via induced drag from asymmetry.
