All of the combined regions of the planet which support self-sustaining ecosystems The biosphere extends above and below the surface of the Earth, wherever there are living ecosystems
Part of the earth and its atmosphere in which organisms live The biosphere is a very thin layer and includes the land surface and subsurface, the world ocean, and a thin part of the troposphere
The transition zone between the earth and the atmosphere within which most terrestrial life forms are found It is considered the outer portion of the geosphere and the inner or lower portion of the atmosphere
Zone of the Earth where life is found The biosphere consists of all living things, plant and animal This zone is characterized by life in profusion, diversity, and ingenious complexity Cycling of matter in this sphere involves not only metabolic reactions in organisms, but also many abiotic chemical reactions Also called ecosphere
The biosphere is the world's ecological system It is the living part of the earth that is ordered by the dynamic flow of energy into complex systems The energy source for this is the sun, via the photosynthetic processes [3: The Biosphere: Life on Earth ]
All of Earth's living organisms inhabiting and interacting with the physical environment (where the atmosphere, lithosphere, pedosphere and hydrosphere function together and support life)
n: The portion of the earth and its atmosphere in which living organisms exist or that is capable of supporting life 2 All of earth's ecosystems combined into one inclusive unit Also called the "ecosphere " 3 The living organisms and their environment composing the biosphere " all life on earth and the realms that support it, from the outermost reaches of the atmosphere to the deepest trenches of the seas " National Geographic Atlas of the World, 6th Edition
1 the zone of the earth, extending from its crust out into the surrounding atmosphere, which contains living organisms 2 all the living organisms of the earth
(1) the part of the earth and its atmosphere in which living organisms exist or that is capable of supporting life; (2) the living organisms and their environment composing the biosphere
The biosphere is the part of the earth's surface and atmosphere where there are living things. the part of the world in which animals, plants etc can live. Relatively thin life-supporting stratum of the earth's surface, extending from a few miles into the atmosphere to the deep-sea vents of the oceans. The biosphere is a global ecosystem that can be broken down into regional or local ecosystems, or biomes. Organisms in the biosphere are classified into trophic levels (see food chain) and communities
