Map the Nitrogen Cycle

What the nitrogen cycle connects

The nitrogen cycle describes movement between nitrogen-containing reservoirs and changes in chemical form. Process labels explain how nitrogen becomes available to organisms and returns to the atmosphere.

When to use this diagram

Use it to revise ecosystem nutrient cycling or explain how soil organisms connect plants with atmospheric nitrogen.

Label processes precisely

1. Separate forms. Atmospheric nitrogen, ammonium, nitrite, and nitrate are different nodes.
2. Name each arrow. Use a transformation name instead of an unexplained connection.
3. Include decomposers. Show how organic nitrogen returns to the soil cycle.
4. Place organisms carefully. Different microbial processes belong on different pathways.
5. Keep impacts distinct. Show fertilizer and runoff without replacing the core biological cycle.
