Gce Model Questions Vol1 2024 Biology Question 18
Practice objective / multiple choice question 18 from the 2024 Gce Model Questions Vol1 Biology examination.
Two algal species compete in a pond. Species A follows logistic growth with intrinsic rate \(r_{A}=0.4\ \text{day}^{-1}\) and carrying capacity \(K_{A}=1.0\times10^{6}\) cells. Species B has \(r_{B}=0.3\ \text{day}^{-1}\) and \(K_{B}=8.0\times10^{5}\) cells. The competition coefficients are \(\alpha=0.5\) (effect of B on A) and \(\beta=0.7\) (effect of A on B). Assuming the Lotka‑Volterra competition model, which species attains the higher equilibrium population and what is that equilibrium (to two significant figures)?
