here's why leaves turn from green to red in the fall - solar street light cost

Friday, September 22 marks the beginning of autumn, the autumn equinox, which means the beginning of autumn for the Northern Hemisphere.
With the appearance of pumpkin spices, autumn is also known for the beautiful color changes of the leaves.
But why is this happening?
We are glad you asked us.
Newsweek interviewed.
Dennis Stevenson, vice president and curator of plant research at the New York Botanical Garden in New York City, Better understands this amazing phenomenon.
According to Stevenson, unlike most creatures that get energy through food, trees get energy from the sun.
A chemical in the interior of a leaf-chlorophyll, through a process called photosynthesis, converts sunlight into the energy of a tree.
However, during the spring break, the Sun is much less than usual, which means that the trees have less energy.
Stevenson explained that this change in sunlight is the main reason for the fall of leaves.
"The trees are preparing for the winter, which means a shorter time and very cold weather," Stevenson said . ".
"Normally, trees are not able to sustain themselves through photosynthesis, and in addition, they have to deal with the risk of leaf icing.
The easiest way to solve this problem is to remove their leaves.
In autumn, the leaves change color because the trees stop a lot of chlorophyll in order to prepare for the winter.
OK, that explains why the leaves fall off, but what about the color change?
The color of the leaves is bright green.
Stevenson explained that most of the leaf colors we see in the fall are caused by the loss of chlorophyll.
To prepare for the dark winter season, and to save energy, the trees again stopped producing as much chlorophyll.
"Normal Green will turn red as plants lose their chlorophyll," Stevenson said . ".
"Green and other pigments such as yellow, red and other various shades can be seen.
"Some strange factors will affect the way and time when the leaves change color.
For example, according to Stevenson, temperature has an effect on the change of leaves.
A warm or cool season scan produces different colors.
"If the weather is a little warmer but dry, your color will not be as bright as the cool dry autumn.
"The presence of unnatural light also affects the color of the leaves of the trees.
Plants located under street lights may not change color like plants in nature.
In the end, the change of leaves is a natural part of the seasonal change and a way for trees to survive in cold and dark winter.
