Ecosystems are dependent on the following abioticNon-living elements of an ecosystem, such as climate, temperature, water, and soil type. or non-living components:
- climateAverage weather conditions over longer periods and over large areas. - the temperature and amount of rainfall are very important for determining what speciesA type of organism that is the basic unit of classification. Individuals of different species are not able to interbreed successfully. can survive in the ecosystem
- soil - the soil type is important as this provides nutrients that will support different plants
- water - the amount of water available in an ecosystem will determine what plants and animals can be supported
The biotic parts of the ecosystem, which include bacteria, flora and fauna, have a complex relationship with the abiotic components - changing one will lead to a change in the other.
