Anaerobic denitifying bacteria - what do they do?
Convert nitrates to atmospheric nitrogen. Used in denitrification.

Nitrogen fixing bacteria - what do they do?
Convert atmospheric nitrogen to nitrogen compounds. Live on root nodules with which they have a mutualistic relationship.
3 of 6
Why do living organisms require nitrogen?
Used to manufacture proteins.
4 of 6
How do plants uptake nitrogen?
Uptake nitrates using absorption, diffusion and active transport via root hairs.

De-nitrifying bacteria - what do they do?
Convert nitrates in the soil to atmospheric nitrgoen. Thrive in anaerobic soil conditions e.g. waterlogged land and compost heaps. Farmers ensure their land is drained.
