NPP at first trophic level would be the GPP for second trophic level. NPP at second trophic level would be GPP for third trophic level. Therefore, 100x(kcal/m2/yr ) would be GPP at second trophic level and 100x×10%(kcal/m2/yr) i.e., 10x(kcal/m2/yr) energy would be GPP at third trophic level.
In an ecosystem if the Net Primary Productivity (NPP) of first trophic level is 100 x ( kcal m^-2 ) yr^-1, what would be the GPP (Gross Primary…
