Answer:
Air found in the soil is trapped in it and is not exposed to the air currents, poor in oxygen and rich in moisture.
Step-by-step explanation:
Air found in the soil is trapped in it and is not exposed to the air currents.
It contains more moisture than the atmospheric air.
It is rich in carbon dioxide and poor in oxygen.
The air found in the soil forms a part of the lithosphere and not the atmosphere.
Nitrogen trapped in the soil is used by the plants to make protein, carbon dioxide is used for the photosynthesis and oxygen is used for the respiration of roots and microorganisms.
