Q. No.In an ecosystem, if the Net Primary Productivity (NPP) of first trophic level is \(100 x\left(\mathrm{kcal} ~\mathrm{m}^{-2}\right) \mathrm{yr}^{-1},\) what would be the GPP (Gross Primary Productivity) of the third trophic level of the same ecosystem?
1. \(x\left(\mathrm{kcal}~ \mathrm{m}^{-2}\right) y r^{-1}\)
2. \(10 x\left(\mathrm{kcal} ~\mathrm{m}^{-2}\right) \mathrm{yr}^{-1}\)
3. \(\dfrac{100 x}{3 x}\left(\mathrm{kcal} ~\mathrm{m}^{-2}\right) \mathrm{yr}^{-1}\)
4. \(\dfrac{x}{10}\left(\mathrm{kcal} ~\mathrm{m}^{-2}\right) y r^{-1}\)
1. \(x\left(\mathrm{kcal}~ \mathrm{m}^{-2}\right) y r^{-1}\)
2. \(10 x\left(\mathrm{kcal} ~\mathrm{m}^{-2}\right) \mathrm{yr}^{-1}\)
3. \(\dfrac{100 x}{3 x}\left(\mathrm{kcal} ~\mathrm{m}^{-2}\right) \mathrm{yr}^{-1}\)
4. \(\dfrac{x}{10}\left(\mathrm{kcal} ~\mathrm{m}^{-2}\right) y r^{-1}\)
