ocean. These microscopic organisms perform photosynthesis, using sunlight to convert carbon dioxide and water into organic matter, releasing oxygen in the process. Diatoms are one of the most common types of phytoplankton, characterized by their intricate silica shells. Dinoflagellates are another type of phytoplankton, known for their ability to move using flagella. These organisms are essential in the oceanic food web, as they are the primary source of food for many marine organisms, including zooplankton, which are then consumed by larger animals. Additionally, the high productivity of these algae in the ocean contributes significantly to the global carbon cycle and the oxygen production in the atmosphere.
