Autogenic succession
In ecology, autogenic succession is succession driven by the biotic components of an ecosystem.[1] In contrast, allogenic succession is driven by the abiotic components of the ecosystem.[1]
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
Facilitation
- Improvement of site factors like increased organic matter
Inhibition
- Hinders species or growth
