4. Abiotic (physical factors) are the influences of the non-living part of the community e.g.. Climate
Abiotic
Desiccation
Aspect
Wave crash
Temperature
Light
Gradient
Salinity
Oxygen

5. The biotic factors are the influences that result from the activities of living organisms in the community eg. competition
