A student researching coral has taken notes:
• Corals are colonies of tiny animals called polyps • Coral reefs are sometimes called the "rainforests of the sea" • A single reef can support thousands of species • Coral bleaching occurs when stressed corals expel symbiotic algae • Healthy reefs protect coastlines from storm damage
The student wants to compare coral reefs to rainforests.
Corals are colonies of tiny animals called polyps that build reef structures.
Like rainforests, coral reefs support extraordinary biodiversity—a single reef can host thousands of species, earning them the name 'rainforests of the sea.'
Coral bleaching occurs when stressed corals expel their symbiotic algae.
Healthy coral reefs protect coastlines from storm damage.
Correct Answer: B
Choice B. Thousands of species and "rainforests of the sea" draw comparison.
