← Nature & AnimalsWhich outcome occurs when an oil slick interferes with marine mammal echolocation?
A)Masking increases predation risk sharply✓
B)Hunting efficiency will remain constant
C)Competition exclusion reduces population density
D)Algal blooms cause auditory hallucinations
💡 Explanation
Masking elevates predation because sound waves scatter unpredictably due to the oil slick. Echolocation depends on consistent sound reflections; therefore, prey become less detectable, and predation increases rather than some hallucination or consistent hunting success.
