Practice objective / multiple choice question 19 from the 2018 Gce Model Questions Vol1 Biology examination.
A population of a herbivorous mammal in a closed reserve follows the logistic growth model \(\frac{dN}{dt}=rN\left(1-\frac{N}{K}\right)\). Field observations give a per‑capita growth rate of \(0.06\) month\(^{-1}\) when \(N=200\) and \(0.02\) month\(^{-1}\) when \(N=800\).\n(a) Determine the intrinsic rate of increase \(r\) and the carrying capacity \(K\).\n(b) If a constant harvest of 30 individuals per month is introduced, find the equilibrium population size(s).\n(c) State whether this harvest level is sustainable.
