1. Energy in lightening splits nitrogen molecules into separate atoms which react with oxygen to form Nitrogen Oxides. These then washed to ground by rain to form nitrates in soil.
2. Nitrogen fixing bacteria (in soil and some plants) fix the gas into compounds.
3. Haber process by industry to produce ammonia (which is then used to make compounds used as fertilisers) from N & H.
- individuals show wide range of variation due to differences in genes
- those with characteristics most suited to environment will survive and reproduce and genes passed on
- law of use and disuse
- law of inheritance of acquired characteristics
- chemical pesticides used in large amounts to prevent pests harming it. Harms environment therefore not sustainable.
