| Abundance | Number of a particular population in a given area |
| Factors affecting ecosystems arising from human activity | Anthropogenic factor |
| Living factors in an ecosystem | Biotic factor |
| Final stable community at the end of the process of succession | Climax Community |
| When succession is not completed due to human activity | Deflected succession |
| Factors that have a greater effect on a population when the population is large | Density dependent |
| Description of where a particular species can be found | Distribution |
| Interaction between the living and non living components in a given area | Ecosystem |
| Factors related to soil | Edaphic factor |
| Type of feeding relationship between a herbivore and plants | Grazing |
| Place where an organism lives | Habitat |
| Competition for resources between organisms of different species | Interspecific Competeion |
| Competition of resources between organisms of the same species | Intraspecific Competition |
| Type of bar chart representing distribution and abundance of organisms | Kite diagram |
| Feeding/living arrangement between two organisms where both benefit | Mutualism |
| Description of the relational position of a species in its ecosystem | Niche |
| Relation ship where one organism feeds from the other living organism | Parasitism |
| Pioneer community | First species to colonise bare rock |
| Feeding relationship where one organism kills and eats the other | Predation |
| Succession which occurs in an area where no previous communities existed | Primary Succession |
| Succession which occurs on land that has been cleared, where communities existed before | Secondary Succession |
| Communities that develop during succession between the pioneer community and the climax community | Seres |
| Animal that does not move, e.g. attached to rocks | Sessile |
| Measure of the spread of data about a mean | Standard deviation |

| Adaptation of plants that enable them to survive dry conditions | Xerophytic properties |
| Organisms who are able to synthesise organic compounds from simple molecules, such as carbon dioxide | Autotroph |
| Organisms who obtain their food and energy from organic compounds | Heterotrophs |
| Organisms who are autotrophic at the start of a food chain | Producer |
| Organisms who are heterotrophic and feed on producers (herbivores) | Primary Consumer |
| Organisms that feed on primary consumers | Secondary Consumer |
| An organism that feeds on dead and decaying matter, including bacteria and fungi | Decomposer |
