Phytoplankton are microscopic marine plants. P hytoplankton, also known as microalgae, are similar to land-based plants in that they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water. Phytoplankton also require inorganic nutrients such as nitrates, phosphates, and sulfur which they convert into proteins, fats, and carbohydrates.
Phytoplankton, also called algae, are producers that photosynthesize, meaning they convert energy from the sun, carbon dioxide, and other nutrients in the water into food for themselves. They contribute up to 50% of the world's oxygen to the atmosphere.Some examples of phytoplankton are diatoms and dinoflagellates, which are responsible for seasonal algae blooms. Zooplankton are consumers that eat other plankton. Examples include copepods, krill, daphnia and jelleyfish.They are an important link between primary producers and higher trophic levels.hytoplankton, also called algae, are producers that photosynthesize, meaning they convert energy from the sun, carbon dioxide, and other nutrients in the water into food for themselves.
