In the process of ammonification, the nitrogen present inside plants and animals in organic form is returned to the soil in the form _________.

Options

A. nitrogen oxide
B. nitrogen dioxide
C. ammonia
D. nitrates

Answer

**Step-by-Step Solution:**

1. **Understanding Ammonification**: Ammonification is a biological process where organic nitrogen from dead plants and animals is converted back into inorganic forms. This process is crucial for recycling nitrogen in the ecosystem.

2. **Role of Microorganisms**: Certain microorganisms, such as Bacillus Ramosus, play a significant role in this process. They break down organic nitrogen compounds, such as proteins, which contain nitrogen.

3. **Degradation of Proteins**: During ammonification, proteins from dead organisms are degraded. This degradation process involves breaking down proteins into amino acids.

4. **Release of Ammonia**: When amino acids are further broken down through a process called deamination, ammonia (NH3) is released. This is a key step in the ammonification process.

5. **Return to Soil**: The ammonia released during this process can either enter the atmosphere or remain in the soil. The ammonia that remains in the soil can be utilized by plants.

6. **Final Answer**: Therefore, in the process of ammonification, the nitrogen present inside plants and animals in organic form is returned to the soil in the form of **ammonia**.

**Answer**: Ammonia
