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

Here is your answer....

The biosphere is a life supporting layer which surrounds the earth and makes plant and animal life possible without any protective device. The ‘organic world or biosphere is that part of the earth which contains living organisms – the biologically inhabited soil, air and water’.

The environment means surroundings. It is a collective term embracing all conditions in which an animal lives. There are two types of conditions—physical or abiotic such as air, soil, water, light, temperature, precipitation and biotic conditions which surround and affect the life of the organisms.

In other words abiotic components of the bio­sphere consist of 3 sub-components viz., lithospheric component (land component), atmospheric compo­nent (air component) and hydrospheric component (water component).

Only summary of these components is reproduced here. It is significant to note that though biotic components of the biosphere are most signifi­cant aspects of the study of biogeography but abiotic components involving land, air and water are also studied in this discipline.
