What Is The Nitrogen Cycle?

The nitrogen cycle is the process by which nitrogen is transformed into nitrates, used by plants and animals in the creation of amino acids and eventually returned to the air. Through the burning of fossil fuels and the use of nitrogen-based fertilisers, humans have greatly increased the amount of nitrogen in the atmosphere. This excess of nitrogen is highly damaging to the environment, causing ocean dead zones and air pollution, among other things.
