Feeding an ocean: diatoms

Diatoms are tiny microalgae which make up a large proportion of phytoplankton (plankton which is more closely related to plants than to animals) living in the world’s waters. More than 100,000 living species of diatoms form the basis of countless food chains, and are eaten by everything from tiny zooplankton (which includes small animals such…
