Statement 1: This statement is correct. The complex structure of dead coral skeletons provides shelter for macroalgae (seaweed), making it difficult for herbivores to access and graze on them. This leads to rapid colonization of the reef by seaweed, which outcompetes juvenile corals.
Statement 2: This statement is also correct. Reefs can recover more easily after disturbances such as cyclones that remove coral but leave a flat surface because young corals can settle and grow without substantial competition from macroalgae. A flat substrate provides a more conducive environment for coral regeneration.
Statement 3: This statement is incorrect. Corals typically spawn just once a year, not multiple times. This limited reproductive frequency gives algae, which can reproduce continuously, a competitive edge in occupying space left by dead coral.
Therefore, the correct statements are 1 and 2 only.
Conclusion: The correct answer is Option B: 1 and 2 Only.
