Q. Productivity is the rate of production of biomass expressed in terms of I. $(kcal\ m)^{- 3}yr^{- 1}$ II. $g^{- 2}yr^{- 1}$ III. $g^{- 1}yr^{- 1}$ IV. $\left( k\ cal\ m^{- 2} \right)yr^{- 1}$ Choose the correct option
A) II
B) III
C) II and IV
D) I and III
Explanation
The rate of biomass production per unit area over a time period by plants during photosynthesis is called productivity. It is expressed in $g^{- 2}yr^{- 1}$ or $\left( k\ cal\ m^{- 2} \right)yr^{- 1}$
