The world is full of trees. Trees that shade us, provide us with oxygen and shelter, and give us food. Their leaves work to gather sunlight and carbon dioxide and make food which enables them to grow. Autumn is a time when many of these trees go through changes to prepare for winter. They begin to shed their leaves and cut off their food making ability. They will become dormant through the colder months of winter, preparing for their buds to open and for new growth to take place the following spring.
There are over 60,000 known species of trees across the world. And the count for individual trees is estimated to be around 3 trillion. Tropical regions tend to have the most biodiversity when it comes to tree species while colder areas tend to have the least. Some trees keep their leaves all year round and are called evergreen trees. Other trees lose their leaves as days grow shorter and winter comes or when the dry season approaches. These trees are known as deciduous, which is from Latin and means fall down. Some of the most common deciduous species are oak, maple, dogwood, and birch trees.
