Answer
Animal respiration is a process that primarily involves the exchange of gases (oxygen and carbon dioxide) and is part of the carbon cycle. However, it does not directly involve the nitrogen cycle.

Answer
Denitrification is a process in the nitrogen cycle that converts nitrates into nitrogen gas. It does not play a role in the carbon cycle.

Answer
Plant photosynthesis involves the conversion of carbon dioxide and water into glucose and oxygen, utilizing sunlight. While it is part of the carbon cycle, it does not have a direct role in the nitrogen cycle.

Answer
The breakdown of urea fertiliser in soil involves the decomposition of nitrogenous compounds, releasing ammonia and ultimately contributing to both the nitrogen cycle and the carbon cycle through organic matter decomposition. This is the correct answer as it connects both cycles.
