Why trees change color in autumn?

each year, with the arrival of autumn comes the time of rest for the trees. The leaves turn yellow gradually wither and fall the ground, remained almost totally inactive the plant until the return of good weather.

The explanation for this phenomenon is quite simple: the case of a living organism, the plant needs to eat and what advantage does the organic substances produced by the leaves. But, as in the case of animals, it also produces waste.

However, while animals can be expelled continuously feed waste, the plant has to keep in their tissues to fall . When it comes time to peel off sheets , the plant draws from them all the substances still usable and communicates substances waste. These are the color of yellow, brown or red tops of the trees .

show is a sad and beautiful at the same time, because it seems as if the trees before naked, covering his party wanted to dress in warm colors and tones.
