Why does the nitrogen cycle never end ?

It is never "completed." There is no end to the nitrogen cycle; Matter can neither be created or destroyed, and nitrogen is no different. Instead, nitrogen is continuously recycled from one form to another. So if the nitrogen cycle doesn't end, what happens to the aforementioned byproducts of nitrification?

Nitrogen is an element vital to all life processes on Earth.  To appreciate the importance of nitrogen in our biosphere, simply realize nitrogen comprises 78% of the atmosphere, and is embedded in every living tissue!   It is a component of amino acids, proteins and nucleic acids.   With the exception of carbon, nitrogen is the most universal element of life  Put simply: Life could not exists without nitrogen.  Aside from organic development, nitrogenous compounds are also required by some organisms for metabolic functions and respiration.  Nitrogen exists in many states.  In its most common gaseous state of N2, nitrogen forms very strong covalent bonds that can only be broken when great force or energy is applied (e.g. seismic event or lightening), or by particular bacteria species which use nitrogenous compounds for metabolism.  The fact is various bacteria are critical to every step of the nitrogen cycle.  It is these bacteria and their specific roles that are of particular interest to reefkeepers. It is never fully "completed." There is no end to the nitrogen cycle; Matter can neither be created or destroyed, and nitrogen is no different. Instead, nitrogen is continuously recycled from one form to another. So if the nitrogen cycle doesn't end, what happens to the aforementioned byproducts of nitrification?

i'm pretty sure it's spores

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
