What is biosphere?

$\Large\frak{\underline{\underline{Answer:}}}$

The biosphere is made from Greek bios life, sphaira. It is the layer of the planet Earth where life exists. The biosphere is one of the four layers that surround the Earth along with the lithosphere (rock), hydrosphere (water) and atmosphere (air) and it is the sum of all the ecosystems.

This layer ranges from heights of up to ten kilometres above sea level, used by some birds in flight, to depths of the ocean such as the Puerto Rico trench, at more than 8 kilometres deep. These are the extremes; however, in general the layer of the Earth containing life is thin: the upper atmosphere has little oxygen and very low temperatures, while ocean depths greater than 1000 m are dark and cold. In fact, it has been said that the biosphere is like the peel in relation to the size of an apple.

Answer:

The biosphere is made up of all living organisms of the Earth, as well as the physical environment in which they live and with which they interact. Most living organisms actually live within a small area in the biosphere, from about 500 m below the ocean's surface to about 6 km above sea level.

It is made up of Geosphere, Hydrosphere and Atmosphere. In the Biosphere there are two types of components Abiotic and Biotic.
