Wetland primary production is a measure of ecosystem metabolism. It quantifies the amount of carbon fixed in the process of photosynthesis and released in the process of respiration by the plants and algae (photosynthetic organisms) in the ecosystem. At the ecosystem level, the total amount of carbon captured and stored via photosynthesis is known as gross primary production , or GPP. Respiration is the cellular process in which the chemical energy contained in organic compounds is converted to useful energy (in the form of adenosine triphosphate, ATP) to maintain cellular activity. The balance of these two processes represents the net carbon fixed into organic compounds, or net primary production (NPP), which can be used to build biomass.
