Examine the diagram to understand the nitrogen cycle processes depicted. The diagram shows the transformation of nitrogen through different forms and processes.
Identify the process labeled as '1'. This process converts atmospheric nitrogen (N₂) into ammonium (NH₄⁺). This is known as nitrogen fixation, where atmospheric nitrogen is converted into a form usable by plants.
Identify the process labeled as '2'. This process involves the conversion of organic nitrogen from detritus into ammonium (NH₄⁺). This is known as ammonification, where organic matter is decomposed to release ammonium.
Identify the process labeled as '3'. This process involves the conversion of nitrate (NO₃⁻) back into atmospheric nitrogen (N₂). This is known as denitrification, where nitrate is reduced and released as nitrogen gas.
Based on the identified processes, the correct sequence for the diagram is: 1 – nitrogen fixation, 2 – ammonification, 3 – denitrification.
