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.
