| Front | What happens in nitrogen fixation? |
|---|---|
| Back | - lightning forms nitrate from N2 in the atmosphere - haber process forms ammonia from N2 and H2 - free living nitrogen-fixing bacteria - reduce nitrogen gas to ammonia - use ammonia to synthesise amino acids - amino acids released into soil when they die - mutualistic nitrogen-fixing bacteria - in root nodules of legumes - obtain carbohydrates form plants for energy - plants obtain amino acids |
