| Carrying Capacity | Number of individuals of a species a particular environment can support indefinitely |
| Cellular Respiration | metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine tand then release waste products. |
| Climax Community | An ecological community in which populations of plants or animals remain stable and exist in balance with each other and their environment |
| Commensalism | an association between two organisms in which one benefits and the other derives neither benefit nor harm. |
| Consumer | Consume food |
| Cyclic Growth | |
| Decomposers | an organism, fungus, or invertebrate, that decomposes organic material. |
| Density Dependant Factors | factors where the effects on the size or growth of a population vary with the density of the population itself |
| Density Independant Factors | Any factor limiting the size of a population whose effect is not dependent on the number of individuals in the population |
| Ecological Succession | The observed process of change in the species structure of an ecological community over time |
| Energy Flow | The flow of energy through a biological food chain. |
| Exponential Growth | Growth whose rate becom more rapid in proportion to the growing total number or size. |
| Logistic Growth | Over time the population size increases until the population size equals the carrying capacity |
| Mutualism | Symbiosis that is beneficial to both organisms involved. |
| Parasitism | Non-mutual symbiotic relationship between species, where one species, benefits while the other is harmed |
| Photosynthesis | The process by which green plants use sunlight to synthesize foods from carbon dioxide and water |

| Steady State | unchanging condition in a physical process |
| Symbiosis | Interaction between two different organisms living in close physical association, typically to the advantage of both. |
