Answer:

The correct answer is -

Step 1 -  photosynthesis, promotes the movement of the carbon cycle because the energy in is sunlight

step 2 - cell respiration, promotes the movement of the carbon cycle the energy out for cell respiration is heat.

Explanation:

Step I is the photosynthesis / Calvin cycle  and  step II is (cellular) respiration / citric acid cycle / Krebs cycle.  Both processes have their particular carbon input and output and the role of energy is also specific to the process.

During Photosynthesis CO2 is the input of carbon in the carbon cycle  that Uses solar or light energy come from sunlight or  ATP molecules come from light reactions and carbon output is Organic molecules such as glucose or sugars.

During (Cellular)  Respiration  Organic molecules are the carbon input of the carbon cycle that is broken down uses chemical energy and leads to ATP production  and CO2 is carbon output in the carbon cycle.
