Gce Model Questions Vol1 2021 Biology Question 20
Practice objective / multiple choice question 20 from the 2021 Gce Model Questions Vol1 Biology examination.
Ecosystem A has a primary‑producer biomass of 5000 g m⁻², a herbivore biomass of 500 g m⁻² and a carnivore biomass of 50 g m⁻². Ecosystem B has a primary‑producer biomass of 8000 g m⁻², a herbivore biomass of 400 g m⁻² and a carnivore biomass of 80 g m⁻². Assuming that the energy transfer efficiency between successive trophic levels is given by the ratio of the consumer biomass to the resource biomass, calculate the average trophic‑transfer efficiency for each ecosystem (average of the producer→herbivore and herbivore→carnivore efficiencies) and state which ecosystem has the higher overall average efficiency.
