The correct Answer is:
To solve the question "The conversion of nitrate to nitrogen is called," we can follow these steps: ### Step 1: Understand the Terms First, we need to understand the terms related to nitrogen cycling in the environment. The key processes involved are nitrification, denitrification, ammonification, and nitrogen fixation. ### Step 2: Identify the Processes - **Nitrification**: This is the process where ammonia (NH3) is converted into nitrite (NO2-) and then into nitrate (NO3-). This process does not involve the conversion of nitrate to nitrogen. - **Denitrification**: This is the process where nitrate (NO3-) is converted into nitrogen gas (N2) and released into the atmosphere. This is the process we are looking for. - **Ammonification**: This process involves the conversion of organic nitrogen (from dead organisms) into ammonia (NH3). It does not involve nitrate. - **Nitrogen Fixation**: This is the process of converting atmospheric nitrogen (N2) into ammonia (NH3). Again, this does not involve the conversion of nitrate. ### Step 3: Conclusion Based on the definitions and processes described, the conversion of nitrate to nitrogen is specifically referred to as **denitrification**. ### Final Answer The conversion of nitrate to nitrogen is called **denitrification**. ---
