Answer 1

The three correct answers that accurately describe coral reefs are:

1. Coral reef ecosystems are among the most biodiverse on Earth.
2. Coral reefs are sturdy structures that can exist for thousands of years.
3. Coral reefs often are located in nutrient-poor waters.

(While it’s true that coral reefs can thrive in nutrient-poor waters, they typically receive additional nutrients from symbiotic relationships with algae, but they are still adapted to these conditions. The wrong options are those emphasizing low biodiversity or short lifespans.)
