Unregulated populations "J-shaped curve"

Description
- Natality = births within the population
- Mortality = deaths within the population
- Immigration = arrival of individuals from outside the population
- Emigration = departure of individuals from the population
- Population growth rate formula =
(Crude birth rate – Crude death rate) + (Immigration rate - emigration rate) = population growth rate
- Steady growth rates cause exponential population growth
- Something increases by a fixed percent
- Graphed as a J-shaped curve
- Exponential growth cannot be sustained indefinitely
- It occurs in nature with a small population and ideal conditions
