Answer 1

Correct:
- Coral reefs are found in warm, shallow ocean water.
- Coral reefs support a huge variety of organisms.
- Coral reefs protect beaches and shorelines from waves.

Incorrect:
- Coral reefs contain a mix of fresh water and salt water. (Reefs are marine—saltwater—ecosystems.)
- Coral reefs are home to anglerfish. (Most anglerfish are deep‑sea species; though a few relatives like frogfishes live on reefs, “anglerfish” generally refers to deep‑water forms.)
