Consider the following statements:

  1. 1.Most of the world's coral reefs are in tropical waters.
  2. 2.More than one-third of the world's coral reefs are located in the territories of Australia, Indonesia and Philippines.
  3. 3.Coral reefs host far more animal phyla than those hosted by tropical rainforests.

Which of the statements given above is/are correct?

  1. A.1 and 2 only
  2. B.3 only
  3. C.1 and 3 only
  4. D.1, 2 and 3
▶ Answer & Explanation

Correct answer: D. 1, 2 and 3

Coral reefs thrive in shallow, warm, tropical waters where sunlight penetration is adequate for photosynthesis by symbiotic algae. A significant portion of the world's reefs are concentrated in the Indo-Pacific region, particularly around the Coral Triangle, which includes Australia, Indonesia, and the Philippines. While coral reefs are exceptionally biodiverse, hosting a large number of species, the statement that they host *more animal phyla* than tropical rainforests is generally considered accurate due to the high degree of specialization and unique evolutionary paths in these marine ecosystems.
