Question

Diatoms are also called as ‘pearls of ocean’, why? What is diatomaceous earth?

Answer 1

Diatoms are known as ‘pearls of the ocean’ as they are the main producers in the marine environment. Since the walls of the diatoms are made up of silica, a large amount of cell deposits is left behind in their habitat. The accumulation of these cell deposits is called diatomaceous earth. Due to its gritty nature, diatomaceous earth is used for polishing and filtration of oils and syrups.
