In ecology, autogenic succession is succession driven by the biotic components of an ecosystem.〔 In contrast, allogenic succession is driven by the abiotic components of the ecosystem.〔 == How it occurs == The plants themselves (biotic components) cause succession to occur. * Light captured by leaves *Production of detritus *Water and nutrient uptake *Nitrogen Fixation These aspects lead to a gradual ecological change in a particular spot of land, known as a progression of inhabiting species. Autogenic succession can be viewed as a secondary succession because of pre-existing plant life. http://www.epa.gov/ecopage/upland/oak/oak94/Proceedings/Platt1.gif 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「autogenic succession」の詳細全文を読む スポンサード リンク
