Waec Model Questions Vol1 2022 Agricultural Science Question 30
Practice objective / multiple choice question 30 from the 2022 Waec Model Questions Vol1 Agricultural Science examination.
A fish population in a lake follows the discrete logistic model N_{t+1}=N_t + r N_t (1 - N_t/K) - m N_t - H, where r = 0.5 yr⁻¹ is the intrinsic growth rate, K = 200 000 fish is the carrying capacity, m = 0.1 yr⁻¹ represents natural mortality, and H is a constant annual harvest (in fish). Determine the maximum constant harvest H (in fish per year) that can be sustained without driving the population to extinction.
