NEET · Biology · STD 12 - 12. ecosystem
Which of the following is the unit of productivity of an Ecosystem?
- A \(\mathrm{gm}^{-2}\)
- B \(\mathrm{KCal m}^{-2}\)
- C \(\mathrm{KCal m}^{-3}\)
- D \(\left(\mathrm{KCal} \mathrm{m}^{-2}\right) \mathrm{yr}^{-1}\)
Answer & Solution
Correct Answer
(D) \(\left(\mathrm{KCal} \mathrm{m}^{-2}\right) \mathrm{yr}^{-1}\)
Step-by-step Solution
Detailed explanation
The rate of biomass production is called productivity. It is expressed in terms of \(\mathrm{gm}^{-2} \mathrm{yr}^{-1}\) or \(\left(\mathrm{KCal} \mathrm{m}^{-2}\right) \mathrm{yr}^{-1}\) to compare the productivity of different ecosystems.
