ii. Explain any two processes involved in the cycling of nitrogen in the environment.​

Answer 1

Answer: here is your answer :-

1. Explanation:  The circulation of carbon is important in Nature because of the following reasons:• Carbon is a life-sustaining element for living organisms like plants. Carbon is an essential element to life on the Planet.• Carbon exchange takes place on the earth between the atmosphere to Oceans.• Plants utilize atmospheric carbon to prepare food by the process of Photosynthesis.• The carbon cycle is very essential to keep the normal temperature on the earth.• Animals stored carbon in their bodies release CO2 during the respiration process.

     2. Explanation :- It is defined as an anaerobic (without oxygen) process that catalyzes the reduction of atmospheric nitrogen (N2) into ammonia (NH3). ... The first step is the oxidation of ammonia to nitrate, done by microbes termed as ammonia-oxidizers. The second step is the oxidation of nitrite (NO2–) to nitrate (NO3–).
