What would the atmosphere be like without the biosphere List to different ways

Answer 1

Answer:The biosphere is made up of the parts of Earth where life exists. The biosphere extends from the deepest root systems of trees, to the dark environment of ocean trenches, to lush rain forests and high mountaintops.

Scientists describe the Earth in terms of spheres. The solid surface layer of the Earth is the lithosphere. The atmosphere is the layer of air that stretches above the lithosphere. The Earth’s water—on the surface, in the ground, and in the air—makes up the hydrosphere.

Since life exists on the ground, in the air, and in the water, the biosphere overlaps all these spheres. Although the biosphere measures about 20 kilometers (12 miles) from top to bottom, almost all life exists between about 500 meters (1,640 feet) below the ocean’s surface to about 6 kilometers (3.75 miles) above sea level.

Origin of the Biosphere

The biosphere has existed for about 3.5 billion years. The biosphere’s earliest life-forms, called prokaryotes, survived without oxygen. Ancient prokaryotes included single-celled organisms such as bacteria and archaea.

Some prokaryotes developed a unique chemical process. They were able to use sunlight to make simple sugars and oxygen out of water and carbon dioxide, a process called photosynthesis. These photosynthetic organisms were so plentiful that they changed the biosphere. Over a long period of time, the atmosphere developed a mix of oxygen and other gases that could sustain new forms of life.

The addition of oxygen to the biosphere allowed more complex life-forms to evolve. Millions of different plants and other photosynthetic species developed. Animals, which consume plants (and other animals) evolved. Bacteria and other organisms evolved to decompose, or break down, dead animals and plants.

Step-by-step explanation:

Answer 2

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.
