- The abundance and distribution of a species within a habitat are determined by a combination of biotic and abiotic factors
- Biotic factors are living factors that influence populations within their community; biotic factors come about as a result of the activity of other organisms e.g.
- Food availability
- Intraspecific competition, arising when individuals of the same species compete for resources
- Interspecific competition, arising when individuals of different species compete for resources
- Cooperation between organisms
The Impact of Biotic Factors on a Community Table
- Abiotic factors are non-living factors that influence populations within their community e.g.
- Light intensity and wavelength
- Turbidity, or cloudiness, of water
- Soil or water pH
- Soil or water salinity
- Soil composition
- Oxygen or Carbon dioxide concentration
