Life as we know it:
The basic requirements of life

Life on Earth can survive some really harsh conditions. Life on Earth can survive in temperatures of -130 degrees to +130 degrees. Life on Earth can survive in pressures from a hundred times less the pressure at the surface of the Earth, to pressures of a thousand times the pressure at the surface of the Earth, at the bottom of the sea.

Plants on Earth absorb carbon dioxide from the air and release oxygen. Some plants also release nitrogen into the environment.

Bacteria on Earth can even survive in environments without oxygen!
