The biosphere is the thin life-supporting stratum of Earth’s surface, extending from a few kilometres into the atmosphere to the deep-sea vents of the ocean. It is composed of living organisms and nonliving factors from which the organisms derive energy and nutrients.
What is biosphere? Biosphere refers to the areas or the regions of the Earth possessing life. It is one of the distinguishing features of the Earth from the other planets. The Earth consists of four spheres, namely (1) biosphere, (2) atmosphere, (3) lithosphere (geosphere), and (4) hydrosphere.
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.
By the most general biophysiological definition, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere, cryosphere, hydrosphere, and atmosphere.
The biosphere recycles its air, water, organisms, and minerals constantly to maintain an amazingly balanced state; human beings should probably do their best to imitate it. Though the word has a new sound to it, it was first used over a hundred years ago.
The biosphere is where living organisms are found on, above, and below the Earth’s surface. It is thus one large ecosystem characterized by biotic (living things), abiotic (non-living) factors, and energy working together as a single unit.
The biosphere is the region of the earth that encompasses all living organisms: plants, animals and bacteria. It is a feature that distinguishes the earth from the other planets in the solar system. "Bio" means life, and the term biosphere was first coined by a Russian scientist (Vladimir Vernadsky) in the 1920s.
