Practice objective / multiple choice question 41 from the 2018 Waec Model Questions Vol1 Biology examination.
In a forest, a herbivore population follows the logistic growth model N(t)=K/[1+((K-N0)/N0) e^{-rt}]. Initially N0=200 individuals and the carrying capacity K=800. After 6 months the population reaches 500 individuals. (a) Determine the intrinsic growth rate r (per month). (b) A predator is introduced, reducing the intrinsic rate by 25% and the carrying capacity by 15%. Assuming the population at the moment of introduction is 500, calculate the expected population after another 6 months.
