Coral Reef Value
Coral reefs are often called the "rainforests of the sea" because of their remarkable biodiversity. A single reef can support thousands of species, from tiny invertebrates to large fish and sea turtles. Beyond their ecological importance, coral reefs provide significant economic benefits to coastal communities through fishing and tourism. Scientists estimate that reefs provide goods and services worth $375 billion annually worldwide.
Which choice best summarizes the text?
Detailed Explanation
Choice B is correct. The text discusses both ecological value (biodiversity, "rainforests of the sea") and economic value (fishing, tourism, $375 billion).
Key Evidence:
• "remarkable biodiversity" (ecological)
• "$375 billion annually" (economic)
Why others are wrong: A (threats not discussed), C (tourism is a benefit, not threat), D (overstates—turtles are just one example).
