| Commensalism | directly helps one specie but does not affect the other much. |
| Mutualism | benefits flow both ways |
| Interspecific competition | disadvantages flow both ways, 2 different species |
| 3 types of Symbiosis | Commensalism, Parasitism, and Mutualism |
| Intraspecific competition | disadvantages flow both ways. 2 same species |
| Competitive Exclusion | any 2 species that utilize identical resources that cannot co-exist indefinitely. |
| Resource partitioning | the sub dividing of some category of similar resources that lets competing species co exist. |
| Parasitism | Only one-organism benefits and the other gets harmed. |

| Growth Curves (GRAPH) | a graph showing the number of individuals in a population over time. |
| J-Shaped curve | a growth curve that tracks two phases of population growth - the lay phase and the exponential phase. |
| Lag phase | little or no increase in a population |
| Exponential phase | a population increases so rapidly that the number of individuals doubles in specific time interval and keeps doubling an increasingly shorter periods of time. |
| S-Shaped Curve | a growth curve that depicts the period of relative stability in a population that occurs after its lag and exponential. |
| Population density | the number of individuals in a population in a given area at a given time. |
