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

- the only way humans can get nitrogen is via the food we eat - which microbes fix the nitrogen into

- 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
