The forces that stabilize population size and carrying capacity: Environmental Resistance
Common examples of Limiting Factors: Water, Space, Food, Disease
Biotic potential based on quantity not quality: r-selected
Biotic potential based on devoting large amount of energy and resource to caring for and protecting the relatively few offspring - K-Selected
Disappearance of species from Earth: Extinction
Sum total of all organisms in an area: Biodiversity
Population or group of populations whose members share certain characteristics and can freely breed with one another and produce entire offspring: Species
