Hint: These two are the basic processes of the nitrogen cycle. Nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into several chemical forms as it disperses and travels among the atmosphere, terrestrial, and marine ecosystems.
Complete answer:
Note:
Nitrogen Fixation- It is the process of conversion of nitrogen to ammonia by different processes like biological nitrogen fixation, industrial nitrogen fixation, etc.
Ammonification- It is the process of decomposition of organic nitrogen of dead plants and animals into ammonia.
Complete answer:
| NITRIFICATION | DENITRIFICATION |
| The process of conversion of ammonia to nitrite and then further conversion of nitrite into nitrate is called notification. | The process of conversion of nitrate present in soil into nitrogen is called identification. |
| This is an oxidation process where ammonia is first oxidized into nitrite and further nitrite is oxidized into nitrate. | This is a reduction process where nitrate is reduced into atmospheric nitrogen. |
| It is an aerobic process. | It is an anaerobic process. |
| Nitrosomonas, Nitrococcus, and Nitrobacter are the bacteria responsible for nitrification | Pseudomonas and Thiobacillusare responsible for the denitrification process. |
