Question

may i please know the explanation of nitrogen and carbon cycles in brief?

Answer 1

The nitrogen cycle involves three major steps: nitrogen fixation, nitrification, and denitrification. It is a cycle within the biosphere which involves the atmosphere, hydrosphere, and lithosphere. Nitrogen is found in several locations, or reservoirs. It is most prevalent in se

Approximately 78% of air is Nitrogen. Nitrogen is important to life because it is a key part of amino and nucleic acids. Also, it is an important part of ATP, which is the basic energy molecule for living things.

Neither plants or animals can obtain nitrogen directly from the atmosphere. Instead, they depend on a process known as nitrogen fixation. Key players in this process are legumes and the symbiotic bacteria which are associated with the legume's root nodules. These bacteria are known as nitrogen-fixing bacteria. These organisms convert nitrogen in the soil to ammonia, which can then be taken up by plants. This process also occurs in aquatic ecosystems, where cyanobacteria participate.
