The biosphere, speaking generically, is all the living things -- plants and animals -- in the world.

The biosphere is the global ecosystem, the sum of all the planet's ecosystems. This includes the atmosphere (several kilometers), and the land (at least 3000 meters below ground to the depth of several kilometers). It is often referred to as the "zone of life", where all of earths organisms live.

Closed Biosphere (scientific research projects)

The Biosphere is a sealed, self-supporting ecological environment created to study diverse ecosystems in a controlled medium. Large-scale experiments on human systems (Biosphere 2, BIOS-3) were carried out from 1972 to 1991, with only limited success. None showed the capability for long-term self-sufficiency.

the global sum of all ecosystems

The official definition for the word biosphere is " the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms."
