Which of the following is the unit of productivity of an Ecosystem?
Productivity is expressed in energy per unit area per unit time, e.g., $(kcal\,m^{-2})\,yr^{-1}$.
While biomass/standing crop is measured in $g\,m^{-2}$ or $kcal\,m^{-2}$, productivity is a rate metric expressed per unit time: $g\,m^{-2}\,yr^{-1}$ or $(kcal\,m^{-2})\,yr^{-1}$.
