FromAtmosphere (CO₂)

ToPlants (glucose)

Select the Carbon cycle and find Photosynthesis — the process that removes CO₂ from the atmosphere
Select the Nitrogen cycle and find Nitrogen fixation — the process that starts the cycle from atmospheric N₂
On the Carbon cycle, find Combustion — burning fuels, not breathing, releasing CO₂
On the Nitrogen cycle, find Denitrification — the process that returns N₂ to the atmosphere
On the Nitrogen cycle, find Decomposition (putrefaction) — dead matter and waste turning into ammonia
