They produce feed stock
Reduce the production of methane
They come back gastrointestinal worms

The critical zone - The Earth ecosystem is an interaction of several spheres

The biosphere - all the living plants and animals and bacteria.

The lithosphere -which are the inorganic components such as the rocks and sediments.

The atmosphere with the gasses and mainly rainwater together with the energy fluxes Such as temperature or solar radiation.

The hydrosphere - the water and lakes and streams and most important is groundwater in soils and sediment. The area where all spheres interact is defined as the critical zone or the zone that sustains life on earth.


The pedosphere

The soil zone is located in the center of the critical zone.
It is extremely thin compared to the dimensions of the earth and the atmosphere, which is only about 1 to 2 meters in thickness.
