- 20. Multiple ChoiceWhen a specific population grows past the ecosystem's carrying capacity, what happens to the population?Density Independent limiting factors start to occur resulting in the population going farther above carrying capacity.Density Dependent limiting factors start to occur resulting in the population going back below carrying capacity.The population will go extinct due to lack of resourcesThe population grows then finds a new carrying capacity
