The algae grew in number and used more carbon dioxide. Phytoplankton in the sea probably account for more than 50% of global photosynthesis, although there is considerable uncertainty about this estimate.

Phytoplankton have this ability because they contain pigments like chlorophyll, the same chemical found in plants. Like land plants, phytoplankton use sunlight to convert carbon dioxide (CO2) and water into organic carbon and oxygen. CO2 is therefore an essential nutrient for phytoplankton and higher concentrations of CO2 in the surface ocean have the potential to support higher rates of phytoplankton photosynthesis and growth. Elevated p CO 2 has been shown to enhance the growth and photosynthesis of some phytoplankton species which have active uptake systems for inorganic carbon (Giordano et al., 2005; Reinfelder, 2011). Elevated p CO 2 may therefore lead to lowered energetic costs of carbon assimilation in some species and a redistribution of the cellular energy budget to other processes (Tortell et al., 2002). 2 Apr 2008 A widespread species of ocean-dwelling microorganisms has been found to employ a never-before-seen alternative method of photosynthesis.

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. Phytoplankton are a type of microscopic plankton capable of photosynthesis found in oceans, seas, and freshwater, and an essential component of aquatic ecosystems. Phytoplankton can range in size and shape, and since they are photosynthesizing autotrophic organisms, they inhabit waters exposed to sunlight. Although each organism is microscopic, in sufficient numbers, phytoplankton can be observed as colored patches at the surface of bodies of water, or where two currents meet, due to the Phytoplankton primary production (PP) is the principal engine of the biological pump that determines the magnitude of CO2 draw down from the atmosphere and export of fixed carbon in the euphotic zone to the deep ocean. Phytoplankton remove carbon dioxide from the water for photosynthesis. Carbon dioxide is acidic in water, and the pH of pond water will increase during the day as phytoplankton remove carbon dioxide for phososynthesis.
