Leaves of sun plants use a number of tactics to reduce the amount of light they absorb from strong sun rays while leaves of shade plants use opposite tactics to increase the amount of sun radiation they absorb. So if leaves of a sun plan receives 7 times more radiation than leaves of a shade plant, they would absorb only 4 times more radiation than those of the shade plant. This is an interesting phenomenon. People who are rich may waste a lot of their food or wealth while those who are poor can be much more efficient and make much better use of the resources available for them.
