WebA Net Ecosystem Productivity. NEP, or the net change in carbon storage in the ecosystem, includes fluxes from vegetation, detritus, and mineral soil and is an important descriptor of the overall functioning of ecosystems. NEP quantifies carbon accumidation or loss and, because carbon and nutrient cycles are strongly coupled, allows inferences ... In ecology, the term productivity refers to the rate of generation of biomass in an ecosystem, usually expressed in units of mass per volume (unit surface) per unit of time, such as grams per square metre per day (g m d ). The unit of mass can relate to dry matter or to the mass of generated carbon. The productivity of autotrophs, such as plants, is called primary productivity, while the productivity of heterotrophs, such as animals, is called secondary productivity.

WebProductivity is a rate function, and is expressed in terms of dry matter produced or energy captured per unit area of land, per unit time. It is more often expressed as energy in calories/cm 2 /yr or dry organic matter in g/m 2 /yr (g/m 2 x 8.92 = lb/acre). Hence, the productivity of different ecosystems can be easily compared.
