Question

compare between Nitrogen and carbon cycles in:

1- bacteria names and its roles

2- elements

3- gases

4- aerobic and anaerobic conditions

5- beneficial of these cycles

Answer 1

Difference between nitrogen and carbon cycle:---

Difference	nitrogen cycle	carbon cycle
1. Bacteria name's and its role	Nitrogen fixing bacterias like azotobacter, Rhizobium fixes atmospheric Nitrogen into nitares and nitrite. Nitrosomonas - converts ammonia to nitrites (NO2-) Nitrobacter oxidizes nitrites (NO2-) into nitrates (NO3-) pseudomonas reduces nitrates into Nitrogen gas.	Methanogens - converts oragnic matter like glucose into Co2 and CH4 ( methane) Acedogens convert sugar and amino acid into carbon dioxide.
2 elements	N2, Nitrogen	C, carbon
3 Gases produced	Nitrous oxide (N2O), Nitric oxide(NO), Nitrogen gas	Co2, carbon dioxide, methane(CH4), oxygen (O2)
4. Anaerobic & aerobic conditions	Anaerobic conditions - the process of Nitrogen fixation and denitrification takes palce in anerboic conditions.	Anaerobic conditions for the decomposition reaction by methanogens.
5. benefits of these cycles	it is very important as no living organisms can itself fix or utilise the atmospheric Nitrogen. and Nitrogen is one of the essential component in the body as it acts as building blocks by making a part of proteins amio acids, RNA, DNA etc	carbon cycle is very important as it provides the fuels to the plans for the process of photosynthesis and so helps in production of organic substances i.e. food for all. It helps in maintaining and balancing the excess amount of carbon dioxide in nature, and when it dissolves in water it can be utilised my calcareous animal for making their exoskeleton.
