Carrying Capacity and Limiting Factors

What happens if a population grows past its carrying capacity?

• The population keeps growing

• The population starts to die off

• The entire species will go extinct

• The carrying capacity just increases

Something that regulates the size of a population is called...

• carrying capacity

• biodiversity

What are factors that affect carrying capacity?

• Biotic only

• Biotic and abiotic

• Depends on the ecosystem

• Abiotic only
