| The number of individuals in a population that an environment can support over a relatively long period of time | Carrying Capacity |
| A factor that affects all populations regardless of their population density | Density-independent limiting factors |
| The interaction between organisms in which one species captures and eats another species | Predation |
| A collection of interacting populations within a given ecosystem | Community |
| A symbiotic relationship in which both organisms benfit | Mutualism |
| A relationship in which two different organisms live in close association | Symbiosis |
| A symbiotic relationship between two organisms in which one species harms the other | Parasitism |
| A relationship in which one organism benefits from an interaction and the other is neither helped nor harmed | Commensaliam |
