Question

Besides corals, the coral reefs are formed by

• A. Diatoms
• B. Desmids
• C. Red algae
• D. Brown algae

Answer 1

The correct option is A Diatoms

Diatoms are a major group of eukaryotic micro algae and are one of the most common types of phytoplankton. They are especially important in oceans, where they are estimated to contribute up to 45% of the total oceanic primary production and 25% of the global output. Hence, besides corals, the coral reefs are formed by the diatoms.

So, option A is the correct option.
