4 Range of ToleranceThe range of environmental conditions in which an organism can live and reproduce.
5 Where will you find the greatest diversity? Least # of organisms?
6 Are biotic or abiotic factors that LIMIT the growth of a species. ComparisonLimiting FactorsRange of ToleranceAre biotic or abiotic factors that LIMIT the growth of a species.Determined by the limiting factors that affect a species.
7 Ecological Succession The process by which an existing ecosystem is gradually and progressively replaced by another ecosystem
8 Primary SuccessionThe development of biotic communities in a previously uninhabited and barren habitat with little or no soil.Ex. After lava flow
9 Pioneer Species First organisms to appear in primary succession Help to create the soil by secreting acid to break down rockEx. Lichens (fungi/algae combo) & Mosses
10 Climax Community A relatively stable collection of plants and animals These will change due to environmental factors such as fires, floods, winds, tsunamis, hurricanes, droughts, and other natural disasters.
11 Secondary SuccessionThe development of biotic communities in an area where the natural vegetation has been removed or destroyed but where soil is present.Ex. After a fire
13 The establishment of a community in an area with no soil. ComparisonPrimary SuccessionSecondary SuccessionThe establishment of a community in an area with no soil.The establishment of a new community in an existing ecosystem that was disturbed.
14 Where are the most pioneer species? What usually appears last?
15 BiomesEcosystems identified by their climax community
16 ClimateThe average year-after-year conditions of temperature & precipitation in a particular regionThe variation of climate primarily depends upon the angle of incoming sunlight
