Q2:HW#2: 5.2 Limits to Growth (unlimited)

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

Natural disasters can be considered limiting factors.

• true: density independent limiting factors

• false; natural disasters are not limiting factors

• true: density dependent limiting factors

• false: because Mrs. Burroughs said so
