Practice objective / multiple choice question 50 from the 2020 Neco Model Questions Vol1 Biology examination.
In a lake ecosystem the standing biomass of primary producers is \(5\,000\ \text{kg}\) and their net primary productivity (NPP) is \(800\ \text{kg yr}^{-1}\). Herbivores consume \(30\%\) of the NPP and have an assimilation efficiency of \(60\%\). Carnivores feed on the herbivores with an assimilation efficiency of \(20\%\). (a) Calculate the annual biomass of carnivores that can be supported by this system. (b) If the carnivore assimilation efficiency drops by 5 percentage points, what is the new annual carnivore biomass? Show the difference.
