How Trees Get Ready for Winter
Leaves fall in autumn because trees are getting ready for winter. During warmer months, leaves help trees make food using sunlight. But in autumn, the days get shorter and colder. There’s less sunlight, and the tree can’t make enough food to keep all its leaves alive. So the tree slowly stops feeding the leaves and seals them off, getting ready to rest.
Why the Colors Change Before They Drop
Before leaves fall, they often turn red, yellow, or orange. That’s because the green color (called chlorophyll) fades away, and the other colors that were hiding inside the leaf all along get their chance to shine. After that, the leaves let go and fell to the ground. It’s part of how nature prepares for a fresh start in spring.
FAQs
Q: Do all trees lose their leaves in autumn?
A: No. Trees like pine and fir keep their needles all year. The ones that lose leaves are called deciduous trees.
Q: What happens to the leaves after they fall?
A: Fallen leaves break down and become part of the soil, helping new plants grow. Some animals also use them for warmth.
