What are micronutrients in the carbon cycle?

Micronutrients in the carbon cycle refer to essential trace elements, such as iron, zinc, and manganese, that play crucial roles in the processes of photosynthesis and respiration among plants and microorganisms. Although required in smaller quantities compared to macronutrients, these micronutrients are vital for enzyme function and overall metabolic processes that facilitate carbon fixation and its subsequent release back into the atmosphere. Their availability can influence ecosystem productivity and carbon sequestration capabilities. In this way, micronutrients indirectly affect the dynamics of the carbon cycle and ecosystem health.
