According to the author, noise pollution negatively affects wildlife by hindering which of the following activities?

• A. Migration patterns only.
• B. Feeding rates only.
• C. Nest building and migration.
• D. Mating, establishing territories, and predator-prey interactions.

Answer: (D)

Noise pollution affects wildlife most when it blocks acoustic signals that animals rely on for important social and survival behaviors. Many species communicate through calls, songs, or other sounds to attract mates and to defend or establish a territory; when background noise drowns out these signals, mating success drops and individuals struggle to assert boundaries. Noise also disrupts predator-prey interactions because hearing is crucial for detecting threats or locating prey. If sounds are masked, animals may miss cues that would normally trigger escape, pursuit, or avoidance, leading to mixed or maladaptive responses. Taken together, these disrupted communication and signaling processes directly impact mating, establishing territories, and predator-prey dynamics, which is why that option best captures the author’s point. While migration or feeding can be affected in some cases, they are not the primary activities highlighted.
