We all know that the true sign of autumn is the changing color of the leaves. No offense to festive autumn decorations or holiday drinks such as pumkin spice lattes, but that’s just the way it is, plain and simple. This kind of change is a more chemical one in terms of nature.
To explain everything in more simple terms, trees essentially consume sunlight as if it was a kind of food. When they do this, they also use the process of photosynthesis to convert rays from the sun into other kinds of energy, which, in turn, provides oxygen for the atmosphere of the planet, as well as glucose for other trees. In order for the process of photosynthesis to work, chlorophyll is the biggest aspect that is required, as it will make the leaves of trees turn a lush green color. In order for chlorophyll to work successfully, energy is a big requirement.
Trees also have the ability to watch their weight, especially when the winter months begin rolling around. Trees also get hungry and are also excellent planners in terms of this. Trees will save up huge amounts of energy that they possibly can in order to help them survive throughout both the autumn months and the winter months. They will essentially go on a form of diet in order to increase their odds of survival when reduced amounts of sunlight come as the result of the aforementioned seasons.
Porphyrin is a substance that is contained within chlorophyll, and it’s also one that will begin to break down in the event that there is not enough sunlight for trees to soak up. When porphyrin begins to break down, chlorophyll itself will also begin to break down, which means that other substances such as lycopene and carotene will end up reveaing themselves.
The biggest cause of the vibrant colors of leaves on trees is the amount of sugar that the trees themselves produce. This sugar is what helps trees produce another substance known as anthocyanin, which is a form of pigment. Anthocyanin is typcally boosted by amounts of sunlight. This means that a day during the autumn season that is very sunny will also be very vibrant and colorful thanks to the anthocyanin levels being boosted by solar rays. In cases of less amounts of sunlight, the anthocyanin levels will end up producing a less colorful and vibrant look on the trees. When this occurs, the leaves will drop, thus making themselves available to be blown away and out of sight. Gas powered backpack blowers are good for this job but cause such harsh environmental issues that they’re hardly worth it.
All in all, while it may sound rather unbelievable, trees, like people, always have ways of watching their weight. At the same time, this process allows for a much more vibrant autumn season.
