[Campbell Biology P.1247] According to the provided text and Table 53.2, at which population ... | Practice Question

According to the provided text and Table 53.2, at which population size N does a population growing under the logistic model with a carrying capacity K of 1,500 and an intrinsic rate of increase r of 1.0 achieve its highest overall population growth rate dN/dt ?

  • A: N = 250, with a growth rate of +208 individuals per year.
  • B: N = 750, with a growth rate of +375 individuals per year.
  • C: N = 1,000, with a growth rate of +333 individuals per year.
  • D: N = 1,500, with a growth rate of 0 individuals per year.

Explanation

According to the text, 'the overall population growth rate is highest, +375 individuals per year, when the population size is 750, or half the carrying capacity.' This is also clearly shown in Table 53.2.
