Las comunidades bioedaficas estan conformadas generalmente por protistos de la microfauna y microflora, y ademas por organismos de los filones Arthropoda, Annelida y Mollusca; estas comunidades ocupan habitats de bosques, selvas y praderas, donde encuentran humedad y alimento necesario para subsistir, gracias a la sinergia desarrollada entre los diferentes organismos, el clima y el material parental, sobre un relieve especifico y en un tiempo determinado para preservar y, cuando es necesario, recuperar el sistema suelo a traves de su proceso evolutivo.
Acid rain is an example of this: forests are repeatedly exposed to pollutants, in this case acids, which arrive through the atmosphere and have a number of different effects upon the trees, from destroying the leaf cuticles to changing the balance and variety of microfauna in the soil, as well as causing stress in the trees whereby they become weaker and more prone to disease.
By transporting carbon fixed from the tree into the soil, way beyond the fine roots, they are supporting the whole functioning of the decomposer system by providing food for things like bacteria and microfauna.
