Population Size & Ecosystems Terminology

An interbreeding group of organisms of the same species occupying a particular habitat.
Population
1 of 13
The reproductive capacity of a population; the number of new individuals derived from reproduction per unit time.
Birth rate
2 of 13
The movement of individuals into a population of the same species. (11)
Immigration
3 of 13
Species that control their population by competition rather than by reproduction & dispersal.
Equilibrium species
4 of 13
Environmental factors that slow down population growth.
Environmental resistance
5 of 13
A part of the environment of an organism that is living, e.g. pathogens & predators.
Biotic
6 of 13
A part of the environment of an organism that is non-living, e.g. air temperature & oxygen availability
Abiotic
7 of 13
The maximum number around which a population fluctuates in a given environment.
Carrying capacity
8 of 13
The number of individuals in a species in a given area or volume.
Abundance
9 of 13
The area or volume in which the organisms of a species are found.
Distribution
10 of 13
A characteristic community of interdependent species interacting with the abiotic components of the habitat.
Ecosystem
11 of 13
The place in which an organism lives.
Habitat
12 of 13
Interacting populations of 2 or more species in the same habitat at the same time.
Community
13 of 13
