| Term | Definition |
|---|---|
| Population | a species living in a particular geographic area with uniquely adapted individuals. |
| Carrying capacity | the ability of a habitat to sustain a particular population size based on the resources available over a specific period of time. |
| Communities | collections of populations of different species located in the same habitat. |
| Species diversity | a measure of the # and relative density of diff species found in a geographic area. This represents a type of biological census, tallying the species present, their numbers, and their density compared to other species present. |
| Ecosystems | geographic areas that contain collections of communities and habitats. Often defined by dominant plant communities or environmental conditions found there. |
| Transition zone | A locatino where the biological world and environmental conditions of the adjacent habitats blend together. The conditions of the blended habitat support speices and contain ecological niches found in habitats on both sides of the zones. |
| Resource competition | occurs between members of the same species as well a b2wn members of different species for the limited resources available in every habitat. |
| Interspecific competition | competition b2wn members of diff. species. |
| Resource partitioning | a process of subdividing the limited resources within a habitat that ultimately reduces competition intensity between species. |
| Intraspecific competition | an intense form of competitino b2wn memebers of the same species that occurs when there is complete niche overlap. |
| Predation | an interaction in which one animal kills and eats another to obtain its food energy |
| Keystone species | a term usd to describe organisms that have a disproportionally large effect on community structure by helping to regulate the types and numbers of various other species in a community. An example would be a top-order predator |
| Mutualism | a very common relationship between different species in which both species benefit from the interaction, which develops because its results in an increased level of fitness for both speices. |
