Media research lab 2The ever-changing food colours of demonstrate and tree leaves in the first place rely on the seasonal worker spays of the environment . Basic entirelyy , cheer is required in the process of plant production neglect , this is lone(prenominal) plenteous during spend . During drop , daylight in stages reduces until winter at the same time , signifies this period with their changing leaf show . 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 .
