  1. A
    KCal m−3\mathrm{KCal} ~\mathrm{m}^{-3}KCal m−3
  2. B
    (KCal m−2)yr−1\left(\mathrm{KCal} ~\mathrm{m}{ }^{-2}\right) \mathrm{yr}^{-1}(KCal m−2)yr−1
  3. C
    gm−2\mathrm{gm}^{-2}gm−2
  4. D
    KCal m−2\mathrm{KCal} ~\mathrm{m}^{-2}KCal m−2

Correct answer: B

The rate of biomass production, known as productivity, is typically expressed in units such as $\mathrm{gm}^{-2} \mathrm{yr}^{-1}$ or $\left(\mathrm{KCal} \mathrm{m}^{-2}\right) \mathrm{yr}^{-1}$. These measurements allow for the comparison of productivity across various ecosystems.
