| population | All the members of a species living in the same place at the same time |
| density | the number of individuals per unit area or volume (like the # of fish per cubic meter of water in a lake) |
| dispersion | The way a population is disbributed within a given amount of space |
| growth rate | A change in the size of a population over a certain period of time |
| reproductive potential | The maximum number of offspring each member of the population can produce |
| exponential growth | When a population grows faster and faster. |
| carrying capacity | The maximum population that the ecosystem can support indefinitely |
| limiting resource | When a natural resource is consumsed as quickly as it is produced |
| territory | An area defended by one or more individuals against other individuals |
| density dependent | When deaths happen because of overpopulation |
| niche | The unique (special) role a species has inside an ecosystem |
| competition | When different individuals or populations attempt to use the same limited resource |
| predation | When organisms feed on each other and get fed upon. |
| parasite | When an organism lives in or on another organism and feed on it |
| host | The organism a parasite takes its nourishment from. |
| population density | The number of individuals per area |
| dispersion | Refers to Even, Random & Clumped distribution of indiviiiduals in a space |
| growth rate | The birth rate minus the death rate |
| biotic potential | The fastest rate at which a potential population can grow |
| symbiosis | A close, long term association between 2 or more species. |
| mutualism | All participating species that benefit from symbiosis. |
| commensalism | When one species benefits & the other is not affected from symbiosis |
| co-evolution | When 2 or more species evolve in response to each other. |
