       Deciduous trees
       These trees have leaves
       that die and drop off in the
       autumn. In the spring, their
       leaves grow back again.
















       Leaves
       Leaves make the food
       a tree needs to grow.
       They come in all
       shapes and sizes
       depending on the
       type of tree.
