Neco 2020 Biology Question 21
Practice objective / multiple choice question 21 from the 2020 Neco Biology examination.
In a terrestrial ecosystem, the net primary productivity (NPP) is 1500 kcal·m⁻²·yr⁻¹. Only \(60\%\) of this NPP is actually assimilated by primary consumers because \(40\%\) is lost as uneaten material. Of the assimilated energy, \(15\%\) is used for respiration by the primary consumers. The remaining energy is transferred to secondary consumers with an ecological efficiency of \(12\%\). Secondary consumers in turn transfer energy to tertiary consumers with an efficiency of \(8\%\). Calculate the amount of energy (in kcal·m⁻²·yr⁻¹) available to tertiary consumers.
