Limiting Factors of a Population

When 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 resources
• The population grows then finds a new carrying capacity
