When we are talking of population growth we must take into consideration more factors than just growth rate. In the case of exponential growth, we have that the growth rate per capita, that is to say per individual, is constant regardless of the population size, so it grows as the population grows. Meanwhile, in logistic growth, the growth rate per capita creases as the population size approaches a maximum imposed by the limiting resources, that is to say, the carrying capacity of an ecosystem. Therefore we can say that the correct answer is logistic growth.
