Phytoplankton photosynthesis

Ecol. Some of the dissolved carbon dioxide is used in photosynthesis by organisms like phytoplankton. Ocean Exchange; Some animals in the ocean ICES standard for phytoplankton primary production measurements the best way to measure photosynthesis is to look at the absorption of carbon dioxide. In the second part they repeated the iron infusions and it boosted the phytoplankton 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. When all of the carbon dioxide is removed from the water by phytoplankton, bicarbonate will be used as a carbon source in photosynthesis.

The photosynthetic performance of seven phytoplankton species was characterized by four typical photosynthesis–irradiance (P – I) response models. However, the differences were found between the returned values to photosynthetic characteristics by different P – I models. Aquaculturists are well aware that phytoplankton photosynthesis is a major source of dissolved oxygen in ponds.

Phytoplankton growth depends on the availability of carbon dioxide, sunlight, and nutrients. Phytoplankton obtain energy through the process of photosynthesis and must therefore live in the well-lit surface layer (termed the euphotic zone) of an ocean, sea, lake, or other body of water. Phytoplankton account for about half of all photosynthetic activity on Earth. Phytoplankton are responsible for most of the transfer of carbon dioxide from the atmosphere to the ocean. Carbon dioxide is consumed during photosynthesis, and the carbon is incorporated in the phytoplankton, just as carbon is stored in the wood and leaves of a tree. Most of the carbon is returned to near-surface waters when phytoplankton are eaten or decompose, but some falls into the ocean depths. Abstract.
