Neco 2019 Biology Question 35
Practice objective / multiple choice question 35 from the 2019 Neco Biology examination.
Stable‑isotope analysis gives \(\delta^{15}N\) values of \(2\)‰ for a primary producer, \(8\)‰ for a herbivore and \(13\)‰ for a carnivore. The trophic‑level enrichment factor for \(\delta^{15}N\) is \(3.4\)‰ per level. (a) Determine the trophic level of the carnivore. (b) If primary productivity is \(5000\) kcal m⁻² yr⁻¹ and the average energy transfer efficiency between successive trophic levels is \(10\) %, estimate the energy available to the carnivore per square metre per year.
