Please help!! the nitrogen cycle starts with
atmospheric gas being fixed into nitrates
nitrates absorbed by plants
plants passing the nitrogen compounds through to other organisms
decomposers returning nitrogen into soil and atmosphere

Denitrification

Explanation:

In the fifth stage of the nitrogen cycle, nitrogen returns to the air as nitrates are converted to atmospheric nitrogen (N2) by bacteria through the process we call denitrification.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

yes? sounds right, but you didn’t ask a question.
