Phytoplankton /Diatoms and Dinoflagellates

Phytoplankton are microscopic organisms that play a crucial role in the ocean ecosystem. They produce a significant portion of Earth's oxygen and form the base of the marine food chain. Phytoplankton require sunlight and nutrients to thrive and are classified into diatoms and dinoflagellates. Their presence is vital for ocean life, and their absence could disrupt the entire marine ecosystem. Conservation efforts are essential to protect these organisms from pollution and environmental changes.
