Why Do The Leaves Change Color During the Fall?
Some people consider this to be the happiest season of the year. A burst of vibrant color marks the end of summer as trees get ready for their protracted winter hibernation. Tens of thousands of travelers visit the Great Smoky Mountains each year hoping to see nature's breathtaking rebirth for themselves.
The first process is photosynthesis. Leafy vegetation continuously produces chlorophyll in the spring, summer, and early autumn. Chlorophyll is necessary for a plant to be able to convert sunlight into glucose, which in turn nourishes its trees. The leaves are covered with billions of chlorophyll cells, which give them their distinctive green color.
Various Colors That Change
Chlorophyll, however, is not the only element that affects how the colors of fall leaves change. Two further kinds of compounds are carotenoids and anthocyanins, which are also present in diverse leaves and trees. As the days become shorter in the autumn, chlorophyll production decreases, exposing the leaf's "true" hue.
What Causes The Falling Of The Leaves?
Nature's deep 'intelligent' traits may be the source of its beauty. Perennials like trees need to protect themselves in order to withstand the chilly winter temperatures. If trees retained their leaves over the winter, the soft vegetation would freeze, causing harm and perhaps death to the trees.
Trees grow a layer of fresh cells at the base of their leaf stems to block the veins that carry water and nutrients to and from the leaves, protecting their limbs and trunk from the icy winter temperatures. The leaf might now wither and weaken at the stem before falling to its ultimate resting place since water and nutrients are no longer moving back and forth from the leaf.
What Happens To The Fallen Leaves That Hit The Ground?
The Earth is an excellent recycler while also being extremely effective. The water cycle and the slow breakdown of plants and trees into rich soil are only two examples of how little the Earth wastes.
The dense humus that forms on the forest floor as leaves decompose absorbs dew and rainfall. This nutrient-rich "sponge" serves as a reliable supply of water and nutrients for trees and plants, fostering life and plant health throughout the next spring season.
The thick layer of dead leaves in the warm spring and summer months is probably not as useful to the plants, even if they provide protection for the trees in the winter. By following their natural cycle, trees are able to support themselves year after year.
