Give diagrammatic represntation of nitrogen cycle.

Explanation

### Step-by-Step Text Solution for Diagrammatic Representation of Nitrogen Cycle:

1. **Atmospheric Nitrogen**: Begin by drawing the atmosphere at the top of your diagram. Indicate that nitrogen gas (N₂) makes up about 78% of the atmosphere.

2. **Nitrogen Fixation**: Below the atmosphere, illustrate the process of nitrogen fixation. This can be represented by arrows pointing down from the atmosphere to the soil, indicating that nitrogen gas is converted into ammonia (NH₃) through the action of nitrogen-fixing bacteria or lightning.

3. **Ammonification**: Next, show that ammonia in the soil can be converted into ammonium ions (NH₄⁺) through the process of ammonification. You can represent this with a label or a small arrow leading to ammonium ions.
