what would the atmosphere be like without the biosphere list to different ways

Without the biosphere, the atmosphere would not exist. This is because the biosphere is a layer on the earth where interactions between living beings and all elements such as gases, relief, climate, water, nutrients, among others, take place. In short, it is in the biosphere that all living beings and the natural elements that allow life on our planet exist.

In addition, the biosphere is constituted by the hydrosphere, atmosphere and lithosphere. The atmosphere, in turn, is composed of a layer of gases. As we know, there is a gas exchange between living beings and the atmosphere, which allows living beings to survive and that the atmosphere has an adequate concentration of gases to maintain life on earth. For this reason, we can affirm that without the abiosphere, the atmosphere would not exist.
