Step 1
I'll explain the differences between C^3 and C^4 plants in a clear, step-by-step manner:

Step 2
: Photosynthetic Carbon Fixation Mechanism

C^3 and C^4 plants differ fundamentally in how they initially fix carbon dioxide during photosynthesis: - C^3 plants use the Calvin cycle with a single carbon fixation step - C^4 plants have an additional preliminary carbon fixation mechanism

Final Answer

C^4 plants have a more complex carbon fixation process that allows them to be more efficient in hot, dry environments compared to C^3 plants.
