extremely rapid growth of a species when resource plentiful, produces a J-curve when graphed exponential growth
reproductive potential of a species, represents the maximum rate at which a species can reproduce when not limited by environmental factors biotic potential
total of factors which prevent a species from reaching its biotic potential (weather, disease, etc.) environmental resistance
density-dependent controls on population limit population size as number increase (ex. disease)
density-independent controls on population limit population size regardless of numbers (ex. flood)
ability of an organism to repopulate an area following a disturbance resilience
too much or too little of any one thing can limit an individual, population, or entire ecosystem limiting factor principle
Law of tolerance there are maximums and minimums beyond which an organism can’t survive
