← Nature & AnimalsWhich outcome reduces soaring efficiency when damage disrupts feather alignment?
A)Induced drag sharply increases✓
B)Lift-to-drag ratio maintains stability
C)Metabolic energy decreases slowly
D)Air sacs provide more buoyancy
💡 Explanation
When feather barbules are damaged, profile drag significantly increases because optimized airfoil contours are disrupted triggering induced drag, therefore soaring efficiency reduces, rather than buoyancy as air sacs relate to respiratory capacity or lower energetic effort in flap frequency alone.
