According to Vernadsky, the biosphere is an external Earth cover, the 'scope of life'. He also noted that this definition is not complete. The vernadsky's biosphere includes
- living matter
- 'biogeneric matter',that is, organic and mineral substances, created by living matter
- 'bioinert matter', created by living organisms together with inorganic nature
The biosphere is defined as the zone where both living organisms and the products of their activities are found. So it plays an important role to maintain the ecosystems, that is the life of organisms and their mutual interactions. And biosphere is very important to regulate the climate. Changes in the biosphere results the changes in climate. The biosphere is an important reservoir in the carbon cycle.
