Diatoms in the ocean
WebPhytoplankton are microscopic plants, but they play a huge role in the marine food web. Like plants on land, phytoplankton perform photosynthesis to convert the sun’s rays into energy to support them, and they take in carbon dioxide and produce oxygen. Because they need the sun’s energy, phytoplankton are found near the water’s surface. WebJun 12, 2013 · A diatom is a photosynthetic, single celled organism which means they manufacture their own food in the same way plants do. They are a major group of algae and form one of the most common forms of phytoplankton and join the myriad of organisms that drift on currents in the upper layers of the ocean and lakes.

This substance, produced throughout the shark's body, counterbalances the salt in the ocean water. In other words, there's as much salt in the seawater as there is urea (and other chemicals) in the water inside the shark's tissues.
