The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple chemical forms as it circulates among atmosphere, terrestrial, and marine ecosystems. The conversion of nitrogen can be carried out through both biological and physical processes.

 Phosphate is not the part of nitrogen cycle. Option C is correct. Nitrogen cycle consist of four parts :

1)Assimilation

2)Ammonification

3) dentrification

4) nitrification

Nitrogen cycle is also known as biogeochemical cycle . In nitrogen cycle conversion of nitrogen take place into a multiple forms . The conversion take place with the help of chemical and physical process.

the answer is 95 degrees
