Respiration and photosynthesis have least effect on the cycling of

In the nitrogen cycle

Explanation:

Photosynthesis and respiration in plants are almost opposite processes. In photosynthesis, water (H2O) and carbon dioxide (CO2) are combined using solar energy to form carbohydrates (CH2O), while in breathing, carbohydrates break down, with water as a byproduct, for Energy production. None of these processes involve nitrogen.
