Exponential growth curve
unlimited amount of resources
Logistic growth curve
the population has leveled out
On day 23 the population has reached its carrying capacity
Density dependent factor
A virus depends upon other organisms to be there to spread
Density independent factor
Examples are floods, tornadoes, they do not depend on a population to happen
carrying capacity
the amount of food, water, and shelter that the environment can provide to support the population
