Phytoplankton obtains its nutrients from the surrounding water, primarily through the process of photosynthesis. They use sunlight, carbon dioxide, and inorganic nutrients such as nitrates, phosphates, and trace metals to produce organic compounds and oxygen. These nutrients are essential for the growth and survival of phytoplankton, and their availability can impact the abundance and diversity of these microscopic organisms in aquatic ecosystems. **

Phytoplankton are located at the surface during the day because they require sunlight for photosynthesis, which is their primary source of energy. By being at the surface, they can maximize their exposure to sunlight. At night, phytoplankton migrate to deeper waters to avoid predation and to access nutrients that have accumulated at the bottom during the day. This vertical migration pattern allows phytoplankton to optimize their access to both sunlight and nutrients, maximizing their chances of survival and growth. **
