← Nature & AnimalsWhich outcome occurs when prolonged soaring flight depletes glycogen stores in a bird's liver and muscles?
A)Reduced lift due to asymmetric drag
B)Increased efficiency in oxygen absorption
C)Fatigue-induced drop in body temperature✓
D)Erratic flight patterns from neural misfiring
💡 Explanation
When glycogen stores deplete during prolonged soaring flight, ATP production through aerobic glycolysis declines, triggering hypothermia because less energy is available for thermogenesis. Therefore fatigue causes a drop in body temperature, rather than asymmetric drag, increased oxygen, or erratic flight, which involve altered flight control mechanisms.
