Denitrification is also called

Options

A. A. putrefaction
B. B. heterotrophic nitrification
C. C. assimilatory nitrate reduction
D. D. dissimllatory nitrate reduction

Explanation

**Step-by-Step Solution:**

1. **Understanding Denitrification**: Denitrification is a process that involves the loss of nitrogen from the soil. It occurs when nitrogen compounds, particularly nitrates, are converted back into nitrogen gas (N2) and released into the atmosphere.

2. **Mechanism of Denitrification**: This process can occur through two main mechanisms: biological and chemical. The biological process is primarily facilitated by certain types of bacteria that break down nitrates.

3. **Role of Bacteria**: The bacteria involved in denitrification play a crucial role in converting nitrates into nitrogen gas. This breakdown leads to a reduction in the nitrogen content of the soil.

4. **Identifying the Alternative Name**: The question asks for another name for denitrification. The alternative name is "dissimilation nitrate reduction." This term reflects the process where nitrates are reduced, resulting in a decrease in their concentration.

5. **Conclusion**: Therefore, the second name for denitrification is "dissimilation nitrate reduction."
