Which of the following is the unit of productivity of an Ecosystem?

Options

  1. Agm−2\mathrm{gm}^{-2}
  2. BKCalm−2\mathrm{KCal m}^{-2}
  3. CKCalm−3\mathrm{KCal m}^{-3}
  4. D(KCalm−2)yr−1\left(\mathrm{KCal} \mathrm{m}^{-2}\right) \mathrm{yr}^{-1}

Correct answer

D. (KCalm−2)yr−1\left(\mathrm{KCal} \mathrm{m}^{-2}\right) \mathrm{yr}^{-1}

Step-by-step solution

The rate of biomass production is called productivity. It is expressed in terms of gm−2yr−1\mathrm{gm}^{-2} \mathrm{yr}^{-1} or \left(\mathrm{KCal} \mathrm{m}^{-2}\right) \mathrm{yr}^{-1} to compare the productivity of different ecosystems.
