nitrogen cycle   Dan carbon cycle

The nitrogen cycle has traditionally been divided into three processes — N2 fixation, nitrification, and denitrification — and

A small amount of nitrogen can be fixed when lightning provides the energy needed for N2 to react with oxygen, producing nitrogen oxide, NO, and Role of Organisms in Nitrogen Cycle · Nitrogen-fixing bacteria, which convert atmospheric nitrogen to nitrates · Bacteria of decay, which convert decaying
