7 wonders of the microbe world - nitrogen fixation (4/7)
in summary
- microbes generate at least 1/2 of the oxygen we breath
- they fix nitrogen - a key building block for life

- fix - take and combine with oxygen or hydrogen into compounds that plants can make use of
- crop rotation uses this relationship to make soil more fertile
