Levels of Biotic Organization

The level of biotic organization may be considered from different perspectives and these are briefly outlined. A merely structural level of the individuals is the most traditional approach, but it must be considered that there is a basic difference between a simple structure that is actually primitive and such highly evolved conditions as obtain in some parasitic or symbiotic organisms. Other levels of biotic organization that have to be considered concern the organization of communities and ecosystems, as well as symbioses. A brief discussion is therefore provided for each of the different aspects that biotic organization may take according the perspective from which it is considered.
