Solution

Diatoms are the major primary producer in the globe. They produce oxygen more than the all the world tropical forests put together

Whatever the oxygen taken inside by us are atleast 1/4 of its from diatoms

Recently freshwater diatoms are also used as bioindicators, to detect the pollution.

They can be used as filters (for wine), abrasives (for toothpaste), and oil (from diaatom beds)

They are the primary producers that trap the Sun\'s energy and thus the basis of all life in the oceans

Hope it helps
