Tolerance : the ability to survive when subjected to biotic or abiotic factors
Population Density : number of organisms per unit area
Dispersion : pattern of spacing of a population within a area
Ecological Succession : when one community replaces another as a result of changing abiotic and biotic factors
Primary Succession : Slower form of ecological succession. Starts with no living organisms present. Only a bare rock on which a moss (pioneer species). From there more and more organisms move in to feed off of the previous organisms.
Climax Community : Stable mature community that results when there is little change in the composition of species
Secondary Succession : This is the faster paced form of ecological succession. Starts off with soil rather than a bare rock. Usually from a natural disaster such as a fire
Density Independent factors : any factor in the environment that does not rely on the number of members in a population per unit area
Density depending Factors : biotic factors that could change population
Population Growth Rate : explains how fast a population grows
Emigration : moving away from a population
Immigration : moving towards a population
Carrying Capacity : maximum number of individuals in a species that an environment can support for the long term
Natural resources : all materials found in the biosphere.
Overexploitation : excessive use of a species with economical value
Habitat fragmentation : separation of an ecosystem into small pieces of land
Biological Magnification : increasing concentration of chemicals going throughout the trophic levels
Introduced Species : nonnative species either intentionally or unintentionally introduced to a new habitat
Polyploidy : one or more extra chromosomes in an organism
Sporangium : sac or case in which spores are produced
Mycorrhiza : mutualistic relationship regarding fungus
Vascular Plants : plants with vascular tissues
Nonvascular Plants : lack vascular tissues
Rhizome : food storage organ
