Most of the time, we will find small animals of 3 millimeters, even one millimeter in length.

There are a multitude of interactions between organisms, for example the fungus supplies the plant with water and nutrients that it could not absorb directly, while it will take advantage of molecules resulting from photosynthesis that the plant is able to do.
The structure of a soil is something very important, it is both the composition of particles more or less fine, more or less large, the interstices inside and it is there that will circulate oxygen, circulate water and the more aggregates there are, the more the soil has fertility, has a capacity to retain nutrients that will be used for plants.
