← Nature & AnimalsWhat outcome occurs due to turbulent airflow as a soaring eagle descends rapidly?
A)Stalling increases loss of lift✓
B)Increased air sac oxygen uptake
C)Decreased convective heat transfer
D)Reduced feather barbule interlock
💡 Explanation
Stalling happens because the angle of attack exceeds a critical value, disrupting *laminar flow*. Therefore, stalling causes loss of lift rather than enhanced lift, and is related to airflow over wings not connected directly to heat transfer.
