| population | group of organisms of the same species that occupy the same geographic place at the same time |
| Emigration | movement of individuals AWAY from a population |
| immigration | movement of individuals INTO a population |
| logistic growth | a small population grows rapidly at first, reaches a carrying capacity and levels off |
| exponential growth | a population trys to take adantage of ideal conditions, grows rapidly, only lasts for a short time |
| k-strategist species | porduces few offspring at a time, care for young, typically larger organisms, long life span |
| r-strategist species | produces as many offspring as possible in a short amount of time to take advantage or and environmental factor. No care given, will not maintain a carrying capacity |
| endangered species | a species in danger of extinction |
| extinction | the disappearance of a species when the last of its members dies |
| limiting factor | in any environment there are factors that will determine how many individuals can survive long term |
| carrying capacity | the maximum number of individuals that an environment can support long term |
| natality | number of surviving individuals born into a population |
| stabilize | to maintain the stability of something |
