Editing Biosphere (section)

=== Narrow definition ===
Geochemists define the biosphere as being the total sum of living organisms (the "[[biomass (ecology)|biomass]]" or "[[Biota (ecology)|biota]]" as referred to by biologists and ecologists). In this sense, the biosphere is but one of four separate components of the geochemical model, the other three being ''[[geosphere]]'', ''[[hydrosphere]]'', and ''[[Earth's atmosphere|atmosphere]]''. When these four component spheres are combined into one system, it is known as the [[Ecosphere (planetary)|ecosphere]]. This term was coined during the 1960s and encompasses both biological and physical components of the planet.<ref>{{cite book|last=Möller|first=Detlev|date=December 2010|title=Chemistry of the Climate System|url=https://archive.org/details/chemistryclimate00mlle|url-access=limited|publisher=De Gruyter|pages=[https://archive.org/details/chemistryclimate00mlle/page/n136 118]–119|isbn=978-3-11-022835-9}}</ref>

The Second International Conference on Closed Life Systems defined ''biospherics'' as the science and technology of analogs and [[model (abstract)|models]] of Earth's biosphere; i.e., artificial Earth-like biospheres.<ref>{{cite book|last=Bebarta|first=Kailash Chandra|date=2011|title=Dictionary of Forestry and Wildlife Science|publisher=Concept Publishing Company|location=New Delhi|page=45|isbn=978-81-8069-719-7}}</ref> Others may include the creation of artificial non-Earth biospheres—for example, human-centered biospheres or a native [[Mars|Martian]] biosphere—as part of the topic of biospherics.<ref>{{cite journal |last1=Nelson |first1=M. |last2=Pechurkin |first2=N.
