Question

which of the following has a positive effect by acting as an artificial reef in some areas?
○ undersea cables
○ fisheries management zones
○ wind turbines
○ unexploded ordinances

Explanation:

To determine which option acts as an artificial reef, we analyze each:

• Undersea cables: Primarily for communication, not artificial reefs.
• Fisheries management zones: Regulatory areas, not physical structures for reefs.
• Wind turbines (offshore): Their bases can attract marine life, forming artificial reefs over time.
• Unexploded ordinances: Hazardous, not intended or beneficial as reefs.

Answer:

Wind turbines
