Gce Model Questions Vol1 2022 Biology Question 9
Practice objective / multiple choice question 9 from the 2022 Gce Model Questions Vol1 Biology examination.
A fish population in a lake follows logistic growth \(\frac{dN}{dt}=rN\left(1-\frac{N}{K}\right)\) with intrinsic growth rate \(r=0.4\) yr⁻¹ and carrying capacity \(K=8000\) fish. A constant harvest removes \(H\) fish each year. Determine the maximum sustainable harvest \(H_{max}\) that still allows a non‑zero equilibrium, and give the equilibrium population size at this harvest level.
