← Nature & AnimalsWhich foraging consequence occurs when a bat's larynx stiffens?
A)Reduced frequency range for echolocation✓
B)Increased energy expenditure resisting gravity
C)Enhanced detection of pulsed radar signals
D)Heightened sensitivity to thermal infrared
💡 Explanation
Reduced laryngeal flexibility limits the bat's ability to modulate its echolocation calls through frequency modulation, because higher and lower frequencies cannot be produced. Therefore it has a narrowed sensing range, rather than enhancing alternative hunting mechanisms.
