Population - the total number of a single interbreeding species in one area

Community -

Biotic potential - the maximum rate at which a species can reproduce given unlimited resources and ideal conditions

Environmental resistance - changes to the environment to reduce and restrict the growth rate, often caused by shortages of important factors e.g. space, food

Carrying capacity - the maximum population an environment can support

Competition - when two or more organisms have to share resources in short supply

Intraspecific - between members of the same species

Interspecific - between members of different species

Niche - the role of an organism in its community including its feeding habits, behaviour and its interactions with the abiotic and biotic components of its environment

Mutualistic association - a relationship between two different species of organism where both gain a nutritional advantage
