• There is only one biosphere on Earth, and that’s Earth…
• The term "biosphere" was coined by geologist Eduard Suess in 1875, which he defined as:[2]– the place on earth's surface where
life dwells.
What’s so special?• A biosphere is a closed system
that is self sustaining. It needs nothing replenished from the outside…it does it all, itself.
• For example: the water cycle….• Photosynthesis and Respiration…
Specific biospheres• When the word Biosphere is followed by a
number, it is usually referring to a specific system or number. Thus:
• Biosphere 1 - The planet Earth • Biosphere 2 - A laboratory in Arizona which
contains 3.15 acres (13,000 m²) of closed ecosystem.
• BIOS-3 was a closed ecosystem at the Institute of Biophysics in Krasnoyarsk, Siberia, in what was then the Soviet Union.
• Biosphere J (CEEF, Closed Ecology Experiment Facilities) - An experiment in Japan.
