d) What do you know about Nitrification Denitrification and Ammonificatio
Answers
Answer:
The conversion of nitrogen can be carried out through both biological and physical processes. Important processes in the nitrogen cycle include fixation, ammonification, nitrification, and denitrification. The majority of Earth's atmosphere (78%) is atmospheric nitrogen, making it the largest source of nitrogen.
Answer:
Nitrification is the biological oxidation of ammonia to nitrite followed by the oxidation of the nitrite to nitrate occurring in separate organisms or direct ammonia oxidation to nitrate in comammox bacteria. The transformation of ammonia to nitrite is usually the rate limiting step of nitrification
Denitrification is the microbial process of reducing nitrate and nitrite to gaseous forms of nitrogen, principally nitrous oxide (N2O) and nitrogen (N2). A large range of microorganims can denitrify. Denitrification is a response to changes in the oxygen (O2) concentration of their immediate environment.
Ammonification refers to any chemical reaction in which NH2 groups are converted into ammonia or its ionic form, ammonium (NH4+), as an end product. Bacteria and related microorganisms derive metabolically useful energy from the oxidation of organic nitrogen to ammonium
