Neco Model Questions Vol1 2022 Biology Question 8
Practice objective / multiple choice question 8 from the 2022 Neco Model Questions Vol1 Biology examination.
A forest ecosystem receives \(2000\ \text{MJ m}^{-2}\) of solar radiation annually. Only 2 % of this energy is captured as gross primary productivity (GPP). Plant respiration uses 60 % of GPP, the remainder is net primary productivity (NPP). Herbivores consume 45 % of NPP, and decomposers return 30 % of the remaining NPP to the soil as mineral nutrients. The rest is stored as biomass, but each year 10 % of the stored biomass is lost by fire. Calculate the amount of energy (in MJ m\(^{-2}\)) stored as biomass after one year.
