← Nature & AnimalsWhich outcome impairs a harbor porpoise locating prey using echolocation within a shipping channel?
A)Masking overlaps prey echo profile✓
B)Attenuation reduces transmit distances
C)Reverberation causes signal dampening
D)Refraction bends emitted ultrasound path ways
💡 Explanation
Excessive vessel noise overlaps the porpoise's echoes, a phenomenon called masking, impeding their ability to discriminate prey signals. Because of the masking effect, the porpoise cannot effectively hunt, rather than being limited by signal distances or distortions from reverberation or refraction.
