In an ecosystem, if the Net Primary Productivity (NPP) of the first trophic level is 100 x kcal m^{- 2} yr^{- 1}, what would be the NPP of the third trophic level, assuming 10% transfer?

Solution & Step-by-step Explanation

Lindeman's 10% law:T1 (Producers): 100 x T2 (Primary Consumers): 10% of 100 x = 10 x T3 (Secondary Consumers): 10% of 10 x = x
