Which Statement Best Describes the Order of the Nitrogen Cycle

Which statement best describes the order of the nitrogen cycle?

A) N₂ is converted to proteins in plants > Proteins are converted to NH₄⁺ through decomposition > NH₄⁺ is converted back to N₂ through nitrogen fixation
B) Plant proteins are converted to N₂ through decomposition > N₂ is converted to NH₄⁺ through nitrogen fixation > NH₄⁺ is converted back to proteins in plants
C) N₂ is converted to amino acids through nitrogen fixation > Amino acids are converted to proteins in plants > Proteins are converted to amino acids through decomposition > Amino acids are converted back to proteins in plants
D) N₂ is converted to NH₄⁺ through nitrogen fixation > NH₄⁺ is converted to proteins in plants > Proteins are converted to NH₄⁺ through decomposition > NH₄⁺ is converted back to N₂ via reverse nitrogen fixation
