I'M INTRESTED IN THE CHEMICAL PROCESS

Between a tree and its fruit is a set of cells called the abcission layer. When it's time for the fruit (and leaves on decidious trees) to fall, the tree sends a message to the abcission layer to let go. This will happen when the fruit is ripe.
It also happens if the fruit becomes infected or damaged and the tree is no longer interested in continuing its growth, and in times of drought when the tree is trying to conserve water.
I apologise on behalf of the first responder. That was an unkind and uncalled for comment.

They fall of the tree so that some idiot like you will pick it up and bite into it.
