Phytoplankton are microscopic, photosynthetic organisms that primarily inhabit the upper layers of oceans, seas, and freshwater bodies. They are crucial for aquatic ecosystems as they produce oxygen and serve as the foundational food source for many marine and freshwater species. Phytoplankton include various types of algae, such as diatoms and dinoflagellates, and play a significant role in the global carbon cycle by absorbing carbon dioxide during photosynthesis.
