How do trees cope with the seasons?
Trees grown rapidly during the spring when the weather is wet and warm but they lose their leaves in the winter. This saves energy. The fallen leaves provide a layer of warmth and protection around the base of the tree and the tree can reuse the nutrients from these leaves too.
How do animals cope with the seasons?

Migration- animals like birds move somewhere warmer, or somewhere with more food
