• Birth Rate
• Death Rate
• Emmigration
• Immigration

This occurs when organisms move out of an ecosystem that is in chaos.

• Immigration
• Emmigration
• Birth Rate
• Death Rate

Any environmental factors that happens in an ecosystem that causes a population w to decrease.

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
