Exponential Growth and Logistic Growth of Populations

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

Logistic population growth can be described as

• growth when resources are limited

• a s-shaped curve

• reaching carrying capacity

• all of the above

Exponential Growth occurs when-

• populations have plenty of food/space

• home to keystone species

• have few evasive species in a habitat

• have little to no competition or predators
