Decomposers, Nitrifying Bacteria, Nitrogen-Fixing Bacteria and Denitrifying Bacteria.
1 of 6
What do the decomposers do?
They decompose proteins and urea and turn them into ammonia.
2 of 6
What does the Nitrifying Bacteria do?
They turn ammonia in decaying matter into nitrates.
3 of 6
What do the Nitrogen-Fixing bacteria do?
They turn atmospheric N2(small 2) into nitrogen compounds that plants can use.
4 of 6
What does the Denitrifying Bacteria do?
They turn nitrates back into N2(small 2) gas.
5 of 6
Where can Nitrogen-Fixing Bacteria live?
