What are the products of the light reactions, and how are they used?

Describe the location and function of the two systems of carbon dioxide fixation in $C_4$ plants.

How do chemoautotrophs obtain organic nutrients?

The curve in Figure $4.16$ shows the effect of temperature increase on the rate of photosynthesis in a typical $C_3$ plant. Construct and explain a curve showing the response of a $C_4$ plant to the same increase in temperature.
