How has the biosphere changed overtime?

Over a long period of time, the atmosphere developed a mix of oxygen and other gases that could sustain new forms of life. The addition of oxygen to the biosphere allowed more complex life-forms to evolve. This exchange of food and energy makes the biosphere a self-supporting and self-regulating system.
