Answer 1

ELLO MATE,

The biosphere (from Greek βίος bíos "life" and σφαῖρα sphaira "sphere") also known as the ecosphere (from Greek οἶκος oîkos "environment" and σφαῖρα), is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth, a closed system (apart from solar and cosmic radiation and heat from the interior of the Earth), and largely self-regulating.[1] 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, geosphere, hydrosphere, and atmosphere. The biosphere is postulated to have evolved, beginning with a process of biopoiesis (life created naturally from non-living matter, such as simple organic compounds) or biogenesis (life created from living matter), at least some 3.5 billion years ago.

Answer 2

Explanation:

All four subdivisions thus represent four major global components of the world ecosystem. These four spheres continuously exchange matter with one another, but obviously there are differences in the relative and total amounts of the natural elements in each orga­nisms take in inorganic nutrients from the soil, water and air; they eliminate their wastes, and their bodies are rendered into inorganic molecules once again. Water and minerals shuttle among the air, land and water with an occasional pause in an organism.

Thus, the biosphere is that part of the earth in which life exists (Hutchinson, 1970). More specifically, the sum of those portions of the hydrosphere, lithosphere and atmosphere into which life pene­trates is the biosphere. However, together with the geological, chemical features of the totality of our habitats, these (air, water and earth, and organisms) are sometimes grouped under the term ecosphere (Cole, 1958).

Biosphere or ecosphere may be thought of as a biochemical system capable of capturing, converting, storing, and utilizing the energy of the sun. Approximately three hundred thousand species of green plants and micro-organisms are recognised as primary producers which utilize inorganic elements and com­pounds to synthesize the organic materials of life.
