1.10) Explain the term Diatoms?
Answers
Answer:Diatom, class Bacillariophyceae, any member of the algal class Bacillariophyceae division Chromophyta, with about 16,000 species found in sediments or attached to solid substances in all the waters of Earth. Diatoms are among the most important and prolific microscopic sea organisms and serve directly or indirectly as food for many animals.
Explanation:Diatoms are a major group of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth's biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The shells of dead diatoms can reach as much as a half-mile deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Depression, which was once made up of a system of fresh-water lakes.
Answer:
a diatom is a photosynthetic single celled organism which means they manufacture their own food in the same way plants do. they are major group of algae and from of the most common forms of phytoplankton and join the myriad of organisms that drift on currents in the upper layer of the ocean and lakes.
