Answer 1

Answer:

Nitrogen Cycle is a biogeochemical process through which nitrogen is converted into many forms, consecutively passing from the atmosphere to the soil to organism and back into the atmosphere. It involves several processes such as nitrogen fixation, nitrification, denitrification, decay and putrefaction.

Answer 2

Answer:

the nitrogen cycle has five steps:

Nitrogen fixation (N2 to NH3/ NH4+ or NO3-) ... Assimilation (Incorporation of NH3 and NO3- into biological tissues) Ammonification (organic nitrogen compounds to NH3) Denitrification(NO3- to N2)
