Leaf Question

What is the heaviest leaf ever recorded on the face of the planet ?
And has it ever killed a spider when it went down dead ?

Do you have the answer ?
Even so, why should you share it ?

Why do leaves change colors ?

Have a look at this snap. Any thoughts on why leaves change their colors. Could the red one here on the photo will slowly be dead after giving such a beauty to the entire body of the tree ? bush ? are leaves like the arms of a tree ? lots of questions here, if you are just not serious enough to answer, would you please go somewhere else where there are no colors...
