The discrete logistic function (the one you can solve with your calculator) has a time lag built in = one
generation. What would a greater time lag do to the outcome?
increase the chances of population exceeding K
decrease the chances of population exceeding K
slow down population growth by decreasing r
increase population growth by increasing r
it would have little/no effect under all circumstances
Which set of values for the intrinsic rate of increase, finite rate of increase, and net
reproductive rate could describe the same growing population?
(Note: you should not need to do any math to figure this one out. Just think through general
interpretations of each parameter)
Or = -0.14, A = 0.87, RO = 0.5
r = 3.0, A = 0.22, RO = 0.5
r = 0.22, A = 1.25, RO = 3.0
%3!
r =
= 0.22, A = -0.14, RO = 0.5
If a population has a constant r = 0.3
Group of answer choices
the per capita rate of population increase continues to accelerate as the population grows
the time necessary for population size to double gets shorter as time goes by since population size is increasing exponentially
the absolute increase (change in population size per unit time) is also constant
the time necessary for population size to double is also constant

- During a one-year period, a population of rabbits has a birth rate of 0.8 and a death rate of 0.1. The rabbit population consists of 50 organisms (at the beginning of the year). Which of the following is true about the rabbit population during this one-1 year period? O The rabbit population would increased by 35 rabbits during this year. O The rabbit population would decrease by 35 rabbits during this year O There would be a total of 500 rabbits at the end of the year 500 rabbits were born during the year.arrow_forwardWrite a generalized model for exponential population growth.

- What is the difference between the exponential (J-shaped) and the logistic growth model (s-shaped)?
