Answer:
Soil
Explanation:
Plants get their nitrogen from the soil. Although nitrogen is present in the air the structure of the molecule is strong and so would require large amounts of energy from the plant to break down.
The breaking down of nitrogen is a process called nitrogen fixation. Bacteria and archaea in the soil convert nitrogen into ammonia; breaking down the tough triple bond of nitrogen to be more readily absorbed by the plant.
This can be possible because we no longer need to use a large hose and spray water on the roads and let the dirty water drain away back into seas and rivers and create water pollution. However, this methods requires a large amount of labor and time.
