What percentage of all marine species rely on coral reefs for habitat?

• A. 10%
• B. 25%
• C. 50%
• D. 75%

Answer: (B)

Coral reefs are incredibly biodiverse ecosystems, often referred to as the "rainforests of the sea." They provide essential habitat for a vast number of marine species. Research indicates that about 25% of all marine species depend on coral reefs at some stage of their life for food, shelter, and breeding. This statistic highlights the critical role coral reefs play in marine biodiversity and ecosystem health. The choice of 25% underscores the importance of these ecosystems in supporting a wide variety of marine life, which includes fish, invertebrates, and other organisms. Such a significant percentage emphasizes why conservation efforts are crucial, as the health of coral reefs directly impacts the survival of many marine species and the overall balance of marine ecosystems.
