Igcse Model Questions Vol1 2020 Biology Question 38
Practice objective / multiple choice question 38 from the 2020 Igcse Model Questions Vol1 Biology examination.
In a grassland ecosystem the total primary production is \(12\,000\ \text{MJ yr}^{-1}\). Energy transfer efficiencies are: \(12\%\) from producers to primary consumers, \(10\%\) from primary to secondary consumers, and \(8\%\) from secondary to tertiary consumers. At each trophic transfer \(5\%\) of the available energy is lost as heat before the next transfer. Calculate the amount of energy (in MJ) that reaches the tertiary consumers each year.
