| Question | Answer |
|---|---|
| population | collection of individuals of the same species in a given area whose members can breed with one another |
| exponential growth curve | graph that shows the phase of population growth during which the size of the population doubles regularly within a certain time period |
| logistic growth curve | graph of a curve that shows the various growth phases experienced by a given population |
| steady state | portion of a logistic growth curve in which the average growth rate is zero |
| carrying capacity | size of a population during the steady state portion of a logistic growth curve |
| density-dependent limiting factor | factor that controls population size and operates more strongly on large populations than on small ones |
| density-independent limiting factor | factor that controls population size regardless of how large the population is at the time |
| community | the populations of organisms living in a given area |
| symbiosis | close relationship between two species in which at least one species benefits from the other |
| commensalism | symbiosis in which one member benefits and the other is not harmed |
| mutualism | symbiosis in which two species live together in such a way that both benefit from the relationship |
