Net primary productivityTotal amount of chemical energy fixed by the processes of photosynthesis minus the chemical energy lost through respiration.

2 |
Net primary productivityThe gross primary productivity minus the energy used by the producers for cellular respiration; represents the storage of chemical energy in an ecosystem available to consumers.
|
3 |
Net primary productivitythe amount of organic material available for consumption in a given area. GPP minus losses due to plant respiration.

Net primary productivityThe amount of energy primary producers (organisms that produce their own food from an external energy source such as the sun) capture and convert to tissue minus the amount they lose in cellular respi [..]

Net primary productivityPlant biomass gain measured in tonnes of carbon per hectare per year, as a product of the energy gained through photosynthesis minus the energy lost through respiration. It is an indicator of the natu [..]

6 |
Net primary productivityTotal primary production, minus the amount consumed in respiration
|
7 |
Net primary productivitythe rate at which biomass accumulates in an ecosystem
|
8 |
Net primary productivity The amount of energy which primary producers can pass on to the second trophic levels, representing the amount of CO2 taken in by a plant minus the CO2 it emits during respiration.
