Final answer:
The lion would be represented in the nitrogen cycle diagram within the process of decay. Decomposers such as bacteria and fungi break down organic nitrogen compounds, releasing nitrogen back into the cycle.
Step-by-step explanation:
The lion would be drawn in the nitrogen cycle diagram within the process of decay.
The decay process involves the breakdown of organic nitrogen compounds into ammonium (NH4+) ions by decomposers such as bacteria and fungi. These decomposers play a vital role in returning nitrogen back to the soil after plants and animals die. The lion would represent the organic matter that undergoes decay, releasing nitrogen back into the cycle.
