What are Phytoplankton? Phytoplankton are mostly microscopic, single-celled photosynthetic organisms that live suspended in water. Like land plants, they take up carbon dioxide, make carbohydrates using light energy, and release oxygen. They are what is known as primary producers of the ocean—the organisms that form the base of the food chain. Because they need light, phytoplankton live near ...
Earth's vast oceans teem with innumerable microscopic plants that make the fertility and abundance of the United States’ Grain Belt look like, well, a drop in the ocean. These tiny phytoplankton are essential to life on Earth, says biologist Sam Laney. “Just like plants on land, phytoplankton do photosynthesis: They…
'Phytoplankton is the plant portion of the plankton, the plant community in marine and freshwater situations, that floats free in the water and contains many species of algae and diatoms. Definition source: National Oceanic and Atmospheric Administration
Ocean color data from the SeaWiFS and MODIS sensors enable researchers to examine the link between phytoplankton blooms and fish and bird health.
Because phytoplankton make their own food using the energy of the sun (in a process called photosynthesis), they are called "producers." That places them at the very base of the food web. Many animals eat plankton directly, or feed on animals that eat plankton. Animals that eat plants or other animals are called "consumers," and bacteria that break down dead plants and animals are called ...

What is the biological carbon pump? When sunlight hits the ocean’s surface waters, it stimulates tiny marine plants called phytoplankton to photosynthesize. This process removes carbon dioxide dissolved in the water as phytoplankton incorporate the carbon as they grow. As carbon dioxide levels in surface waters decrease, water is then able to absorb more carbon dioxide from the atmosphere ...
