If a plant lost light exposure, in what ways would photosynthesis be affected?

Too much light energy would damage plants' biological structure and prevent photosynthesis from happening. This is why the photosynthetic process, in general, shuts down during the hottest hours of the day.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
