An ecosystem is the part of the biosphere formed by a physical environment, the living beings that live in it, and the relationships that they establish between them and with the environment. The two fundamental parts of an ecosystem are the biotope and the community or biocenosis. The biotope and the biocenosis establish complex relationships. a. The biotope is formed by abiotic factors, that is, the non-living parts. It is both the physical space and its characteristics (rainfall, temperature, humidity, substrate). b. The community or biocenosis is formed by the set of living beings in the ecosystem. The relationships that exist between them are biotic factors. Abiotic and biotic factors are the components of the biotope and biocenosis that condition the life of the organisms in the ecosystem. Abiotic factors They are characteristics of the environment and can be physical and chemical. These must comply with some parameters or values to allow life, this is called a range, or tolerance zone. Tolerance limits are the values of these parameters. Beyond them, survival is difficult. The most important physical factors are: temperature, rainfall, humidity, light and pressure. The m...
