This natural position is mainly the resolvent of the tree towards the seasonal change wherein it prep ares itself to store its produced viandss during the abundant periods of summer for its survival period in the winter . As the everyday presence of chlorophyll in the leaves during summer is gratuitous during autumn and winter due to lack of daylight the plant and trees reduces the verbalise pigmentat ion for energy conservation . As an exploit , the colour pigmentation in the leaves decrease thus , allowing the presence of other falsify in its surface to become noticeable .
