AlgaTerra - Diatoms are single-celled algae.They live abundantly in lakes, streams and oceans and exist even in wet habitats as tiny as the bark of a tree. The number of different diatom species, that is their biodiversity, is estimated at 1 million, with only 20 000 species having been described. The ecological significance of these organisms becomes enormous, if you take notice of diatoms producing about 25% of the global oxygen.
