Igcse Model Questions Vol1 2021 Biology Question 23
Practice objective / multiple choice question 23 from the 2021 Igcse Model Questions Vol1 Biology examination.
An undisturbed grassland has a gross primary productivity (GPP) of 1500 g C m\(^{-2}\) yr\(^{-1}\). Plant respiration uses 40 % of the GPP. Of the net primary productivity, 10 % is consumed by herbivores. Each adult rabbit requires 150 g of dry plant material per day, and dry plant material is 30 % carbon by mass. The grassland area is 2 km\(^{2}\). Assuming all the carbon transferred to herbivores is used to support the rabbit population, what is the maximum number of rabbits that can be sustainably supported by this grassland?
