Decomposers decompose matter present in dead plants and animals to ammonia. This ammonia is converted into nitrates which are absorbed by plant roots. This process is called nitrification. Ammonia is converted into nitrates with the help of

Options

A. bacteria
B. fungus
C. protists
D. viruses

Answer

**Step-by-Step Solution:**

1. **Understanding Decomposition**: Decomposers break down dead organic matter from plants and animals. This process results in the formation of ammonia.

2. **Formation of Ammonia**: When decomposers act on dead plants and animals, they convert the complex organic matter into simpler substances, including ammonia.

3. **Nitrification Process**: The ammonia produced is then converted into nitrates. This conversion is essential for the nitrogen cycle, as nitrates are a form of nitrogen that plants can absorb.

4. **Role of Bacteria**: The conversion of ammonia into nitrates is facilitated by specific types of bacteria known as nitrifying bacteria. These bacteria play a crucial role in the nitrogen cycle.

5. **Examples of Nitrifying Bacteria**: Some common examples of nitrifying bacteria include:
- **Nitrosomonas**: Converts ammonia into nitrites.
- **Nitrobacter**: Converts nitrites into nitrates.

6. **Conclusion**: Therefore, ammonia is converted into nitrates with the help of nitrifying bacteria.

**Final Answer**: Ammonia is converted into nitrates with the help of nitrifying bacteria.
