Adaptation of conifers to winter.

Conifers have adaptations that help them survive in colder climates, which is why they are commonly found in the Northern Hemisphere. Conifers are found throughout North America and are also found in Europe and Asia. When many trees are packed close together, it creates a dense forest or thicket. Tightly growing trees can help keep warm in extremely cold and snowy conditions. In winter, sunlight is limited and water is not easily available for plants. Conifers have needles, which are thin waxy leaves that allow them to cook food all year round. The waxiness of the needles helps the wood not lose water before it evaporates.
