Put the steps of the nitrogen cycle in order, starting with the step that removes nitrogen from the atmosphere. n2 is formed via denitrifying bacteria. n2 molecules break apart via nitrogen-fixing bacteria. organic matter decays via decomposers. animals ingest nitrogen in nitrate-containing food after pla
