Question

The dotted line on the accompanying graphrepresents the potential size of a population based on itsreproductive capacity. The solid line on this graphrepresents the actual size of the population.Which statement best explains why the actual populationgrowth is less than the potential population growth?(1 point)a.Resources in the environment are limitedb.More organisms migrated into the population thanout of the populationC.The birth rate gradually become greater than thedeath rated.The final population size is greater than thecarrying capacity

Answer 1

Since the species is not reaching its maximum population, we can think that there is an inhibiting factor in the ecosystem. So if more organisms were to migrate within the population or if the birth rate were to increase, the population would not follow the trend in the image. If the resources of the ecosystem were limited, the population would increase, but then they would start to die due to lack of resources so the graph would have a gaussian bell distribution.

Therefore, the answer is D, since the maximum load of the ecosystem has been reached and although the organisms continue to reproduce, the population cannot increase but neither does it decrease since there are sufficient resources.
