Why Do Trees Shed Their Leaves In Autumn Season?

Trees lose their leaves in autumn because they get ready for winter. It’s like when you take off your coat before going to bed, you want to be cozy and not too warm.

In summer, trees use sunlight to make food through a special process called photosynthesis. But when the days get shorter and cooler in autumn, there's less sunlight. Trees know it’s time to save energy for winter, so they slowly stop making food.

The leaves are connected to the tree by little strings called leaf stems, which act like tiny ropes. When the tree stops using the leaves, it sends a message down those strings, telling the leaves to let go. The leaves then fall to the ground, just like when you let go of a balloon and it floats away.

Once the leaves are gone, the tree uses less energy. It’s like going into sleep mode. This helps the tree stay strong through the cold months ahead.
