  2. Net ecosystem production - Wikipedia

    en.wikipedia.org/wiki/Net_ecosystem_production

    Net ecosystem production (NEP) in ecology, limnology, and oceanography, is the difference between gross primary production (GPP) and net ecosystem respiration. [1] Net ecosystem production represents all the carbon produced by plants in water through photosynthesis that does not get respired by animals, other heterotrophs, or the plants themselves.

  3. Primary production - Wikipedia

    en.wikipedia.org/wiki/Primary_production

    Gross primary production (GPP) is the amount of chemical energy, typically expressed as carbon biomass, that primary producers create in a given length of time.Some fraction of this fixed energy is used by primary producers for cellular respiration and maintenance of existing tissues (i.e., "growth respiration" and "maintenance respiration").

  4. Productivity (ecology) - Wikipedia

    en.wikipedia.org/wiki/Productivity_(ecology)

    The formula to calculate net ecosystem production is NEP = GPP - respiration (by autotrophs) - respiration (by heterotrophs). [22] The key difference between NPP and NEP is that NPP focuses primarily on autotrophic production, whereas NEP incorporates the contributions of other aspects of the ecosystem to the total carbon budget.

    [8]: 124 About half of the gross GPP is respired by plants in order to provide the energy that supports their growth and maintenance. [14]: 157 The remainder, that portion of GPP that is not used up by respiration, is known as the net primary production (NPP). [14]: 157 Total photosynthesis is limited by a range of environmental factors.

    The difference between the light and dark bottle 14 C can be considered the rate of primary productivity; however, due to non-photosynthetic uptake of CO 2 there is debate as to whether dark bottles should be used with the 14 C method or if only a light bottle and a bottle treated with the algicide DCMU should be used. Rates of change in ...
