Igcse Model Questions Vol1 2022 Biology Question 17
Practice objective / multiple choice question 17 from the 2022 Igcse Model Questions Vol1 Biology examination.
A herbivore population follows logistic growth \(\frac{dN}{dt}=rN\left(1-\frac{N}{K}\right)\). In a stable environment \(r=0.4\) month⁻¹ and \(K=800\). After a drought, the carrying capacity falls by 25 % and the intrinsic rate falls by 10 %. The population was at the original equilibrium (\(N=K\)) when the drought began. Using the new parameters, calculate the expected number of individuals after 3 months (round to the nearest whole individual).
