Biosphere - Specific Biospheres

Specific Biospheres

When the word 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, 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.
