In an ecosystem if the Net Primary Productivity (NPP) of first trophic level is 100x (kcal m–2 ) yr–1 , what would be the GPP (Gross Primary Productivity) of the third trophic level of the same ecosystem?
1
\(\rm \frac{X}{10}(kcal\ m^{-2})yr^{-1}\)
2
x(kcal m-2)yr-1
3
10x(kcal m-2)yr-1
4
\(\rm \frac{100x}{3x}(kcal\ m^{-2})yr^{-1}\)
