Which among the above observations is / are correct?
Answer:
1, 2 & 3
Notes:
- Statement 1: Coral reefs are more common in Pacific Ocean in comparison to Atlantic Ocean.: This statement is correct. Nearly 75% of all coral reefs are found in the tropical waters of the Pacific Ocean, compared to 18% occurring in the Indian and Atlantic Oceans. Reasons include higher sea temperatures and expansive shallow ocean floors.
- Statement 2: Largest coral reef of the world is located in Pacific Ocean: This statement is correct. The largest coral reef is actually the Great Barrier Reef located in the Coral Sea off the coast of Queensland, Australia in the Pacific Ocean.
- Statement 3: Coral reefs are among the zones of highest marine biodiversity on Earth: This statement is also correct. Coral reef ecosystems show exceptional diversity of marine species even though they cover less than 1% of the ocean floor. They rival tropical rainforests in terms of biodiversity.
