Waec Model Questions Vol1 2021 Biology Question 15
Practice objective / multiple choice question 15 from the 2021 Waec Model Questions Vol1 Biology examination.
A fish population in a lake follows the logistic growth model \(\frac{dN}{dt}=rN\left(1-\frac{N}{K}\right)\). The intrinsic growth rate is \(r=0.5\) yr⁻¹ and the carrying capacity is \(K=10\,000\) fish. A constant harvest of \(H\) fish per year is applied. Determine the maximum sustainable harvest rate (the maximum value of \(H\) that still allows a positive equilibrium) and give the equilibrium population size at this harvest.
