Diatoms are a very special phytoplankton species created by almighty Allah as a blessing

Diatoms, which can be easily recognized thanks to their surfaces being covered with geometrical shaped siliceous capsules, can be given as an example of single-celled seaweeds that form phytoplanktons, which carry out important functions to protect the atmosphere and ecology. Diatoms, which died in the seas thousands of years ago, form the source for petroleum reserves. In addition, diatoms are an important food source for many water-dwelling beings like fish and whales. Furthermore, they are also responsible for providing vitamin D, which is in fish oil. Allah created this living being as food for fish, and then made it useful for fish and men who use fish as food. As it is known, fish oil is a very valuable nutrient for human growth.
 

Besides these functions, diatoms are also being used for industrial purposes and ensure filtering and insulation for various substances. These organisms are also very effective in making silica, nitrate and phosphate  usable for living beings. Under specific conditions, they can also ensure contaminated  water resources to be purified. While many of these processes cannot even be accomplished in laboratory environments, the working of a single-celled organism, made up of only a cell membrane and chloroplast, is not of course its own ability. It is not even aware of the carbon dioxide outside, the oxygen it produces, the importance of carbon for living things or the vitamin D in fish oil; it only carries out the duties assigned to it using its superior qualities. For this reason, it acts through inspiration. Allah, Who creates the earth, the sky and everything in between with the command “Be”, is the superior power, the One Who gives this inspiration, Who creates it, and Who makes it necessary for the existence of life.
 

“Our Word to a thing when We desire it is just to say to it ‘Be!’ and it is.” (Surat an-Nahl, 40)
