Phytoplanktons and Primary Productivity

Phytoplanktons have a unique ability to sequester dissolved as well as free carbon dioxide from aquatic ecosystems and convert them as storage product. This phenomenon is regarded as the primary productivity of that ecosystem. As proposed by Field et al. (1998), about 50 % of global productivity through carbon sequestration is carried out in aquatic ecosystems due to the comparatively higher solubility of CO2 than O2 in natural water. Falkowski opined that about 98 % of productivity in oceans is accounted for phytoplankton populations. Thus, studies on productivity by phytoplankton populations in natural lotic habitat of estuaries and coasts have gained considerable attention by the plankton biologists.
