Question

Quizplus · Accepted Answer

Coral reefs are known as the "rainforests of the sea" due to their high level of biodiversity, with thousands of different species of fish, invertebrates, and algae living together in a relatively small area. This is similar to the high level of biodiversity found in tropical rainforests on land. The other options (pelagic zone, estuary, and littoral zone) do not have the same level of biodiversity as coral reefs.
