These ecological events occur when populations in a ecosystem decrease because the ecosystem is in chaos.

• Immigration

• Emmigration

• Birth Rate

• Death Rate

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

• Carrying Capacity

• Limiting Factors

• Population Density

• Birth Rate

The total number of individuals a habitat can survive with the resources it has available.

What is the carrying capacity of the graph?

• around 500

• much more than 500

• much less than 500

• around 600

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
