The biosphere is the zone of air, land and water where organisms exist. It is commonly known as the global sum of all ecosystems and consists of several layers including the atmosphere, the lithosphere and the hydrosphere.

The biosphere is the sum of all living matter on the Earth. Highly specialized organisms have adapted to the extreme boundaries of the uppermost atmosphere and lowermost ocean depths.

To determine the extent of a possible protistan 'rare biosphere', Stoeck et al. [5] sequenced about 250,000 eukaryotic-specific V9 variable regions of the SSU rRNA.

Biosphere
In the Gaia hypothesis, James Lovelock stated that the entire mass of living matter on Earth (or any planet with life) functions as a vast homeostatic superorganism that actively modifies its planetary environment to produce the ...

The first three items on this list (atoms, molecules, and macromolecules) will be discussed further in the chapter on chemistry.

biosphere reserves World heritage sites identified by the IUCN as worthy for national park or wildlife refuge status because of high biological diversity or unique ecological features.
biota All organisms in a given area.

Biomes BiosphereThe part of our planet in which life exists and with which it exchanges materials. Includes a small part of the lithosphere (the solid earth) and large parts of the hydrosphere (water) and atmosphere.

Studies by taphonomists (paleontologists who study the transition of animals from the biosphere to the lithosphere; taphonomy literally means "burial laws") have shown that organisms that die on land in lush jungle locales are rarely fossilized.

The UNESCO (United Nations Educational, Scientific, and Cultural Organization) biosphere reserves were established quite some time ago.

The Biology covers the study of all the living beings and their interactions into the biosphere.

Ecological systems are studied at several different levels, from individuals and populations to ecosystems and the biosphere.

This text covers the concepts and principles of biology, from the structure and function of the cell to the organization of the biosphere. It draws upon the world of living things to bring out an evolutionary theme.

The boundaries of the ecosystem studied are dictated by the individual carrying out the study. It may be as large as the biosphere or as small as an enclosed bacterial colony.
Understanding ecological terms ...

Biota: The plants and animals of a specific region or period, or the total aggregation of organisms in the biosphere.

An ecosystem includes all the living organisms in a certain area in addition to the nonliving parts of their environment, which usually includes many different communities. Finally, the highest level of organization is the biosphere-encompassing all ...
