← Nature & AnimalsWhich outcome occurs when increased background noise masks prairie dog vocalizations?
A)Reduced predator detection success✓
B)Increased foraging efficiency nearby
C)Enhanced resource competition avoidance
D)Improved alarm signal discrimination
💡 Explanation
Prairie dog vocalizations are critical for predator detection; masking increases predation risks. Because acoustic masking interferes with the perceptual encoding mechanism, smaller alarm choruses occur, therefore reducing overall group vigilance, rather than improving functions in other domains.
