Which outcome occurs when predator vocalizations elicit alarm calls?

💡 Explanation

Reduced predation occurs because alarm calls prompt group defense via acoustic communication, increasing vigilance. Therefore, the dilution effect increases as each individual’s risk is lower, rather than the predator capturing prey or affecting group size.
