Biosphere

Biosphere

The environment covering the hydrosphere, lithosphere, and atmosphere where life exists or inhabits the Earth. This environment encompasses the upper part of the geosphere, that is, the stone sphere, and the lower layer of the atmosphere. On the land surface, flora and fauna are located in the belt between 3 m below and 30 m above the ground. In the case of seas and lakes, the biosphere covers areas up to a depth of 200 m. Plants get some of their nutrients from the soil in the lithosphere, some from the atmosphere, and some from the hydrosphere. When the plant decomposes, the resulting energy and carbon dioxide are released into the atmosphere, while mineral substances are mixed with soil and water.
