How is primary productivity expressed
WebA) NPP can be expressed in energy/unit of area/unit of time. B) NPP can be expressed in terms of carbon fixed by photosynthesis for an entire ecosystem. C) NPP represents the … WebThe term net ecosystem production (NEP) is used to express net carbon accumulation by ecosystems, which is obtained by subtracting the respiratory costs of all organisms (Rall), including plants, grazers and microbes, from GPP. When NEP is positive (i.e. GPP > Rall), there is a net gain of carbon in the ecosystem. Erosion on hillsides.
