Question | Answer |
group of individuals living at the same place at the same time | population |
the number of individuals of a given species that can be sustained in an area over time | carry capacity |
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 |
range of abiotic conditions within which an organism can survive | range of tolerance |
reproduce late, few, high parental care | K strategists |
reproduce early, many small offspring, little or no parental care | R strategists |
