Why Do Trees Lose Their Leaves in Autumn?

Trees lose their leaves in autumn because they start to get ready for winter. When the days get shorter and it gets colder, trees tell their leaves it's time to go. The leaves change color before falling off, like a goodbye party! This helps them save energy during the cold months.
