2. Bacteria involved in the cycle
 The importance of bacteria in the cycle is immediately
recognized as being a key element in the cycle,
providing different forms of nitrogen compounds
assimilable by higher organisms.

3. Clycle steps
 1. Animals wastes are left in the soil until
the soil cover up the wastes.
 2. Waste is ammonificated: saprobiotic
bacteria.
 3. Nitrogen is mixed with hydrogen
making ammonia.
 4. Then Amonia it Nitrificated an
nitrifying bacteria.
 5.Then nitrogen and oxygen mixed up
making natrite
 6.Then natrite it Nitrificated.
 7.NO3 forms in to nitrate
 8.then it have 2 passages one is for the
plants and the other is denitrification a
bacteria
 9.then nitrogen goes into the
atmosphere
 10. then they are 2 passages 1 to amonia
again and the other get back into the soil
by lighting and create nitrate
 11. the cycle strart again.
