Answer:
The biosphere is defined as the region on, above, and below the Earth's surface where life exists. The biosphere is a narrow zone on the surface of the earth where soil, water, and air combine to sustain life. Life can only occur in this zone. 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. Generally defined, the portion of the universe where all life is found is called the biosphere. Since scientists have not found organisms beyond planet Earth, the biosphere is defined as the parts of Earth where life exists. The biosphere is made of three parts, called the lithosphere, atmosphere and hydrosphere
