Question
In what situation might a continuous-time exponential growth model be a BAD description of how population size grows over time?Group of answer choicesA bacterial culture growing in a laboratory with an unlimited amount of resources.A yeast culture being grown by a PhD student who forgot to feed it before going on holiday.The number of people infected by a virus just after the virus was introduced into the population.The initial phase of a population of rats just after a small number of rats arrived on an island where no rats previously lived.
Solution
A continuous-time exponential growth model might be a bad description of how population size grows over time in the situation of "A yeast culture being grown by a PhD student who forgot to feed it before going on holiday."
This is because exponential growth models assume that resources are unlimited and that the population can continue to grow indefinitely. In this scenario, the yeast culture has been left without food, a necessary resource for growth. Therefore, the population of the yeast culture would likely decrease or stagnate, not follow an exponential growth pattern.
