Abiotic and Biotic Factors. What are Abiotic and Biotic factors? Abiotic factors are non-living factors (environmental) which affect the survival of living organisms. Biotic factors relate to other living organisms in the environment which can affect the survival of other organisms.

Abiotic Factors which affect aquatic environments:
Water absorbs and releases large amounts heat with very little temperature change.
Water tends to have a layered effect with hot water closer to the top whilst the coldest water is on the bottom. This layered effect creates multiple different environments for organisms to occupy.
pH is determined largely by the amount od dissolved carbon dioxide which forms carbonic acid in water.
An increase in carbon dioxide will increase photosynthesis but as a result of the increase in pH many other organisms will die (such as fish)
Transparent water permits light to reach photosynthetic organisms
Cloudy water prevents light reaching these organisms and could result in the death of the plants which in turn will affect the food supply for many other organisms in the food chain.
