All this is possible thanks to the fact that the rainforest has sunlight all year and does not have seasons. This keeps the water cycle working (rains a lot)and the trees can do photosynthesis all year. The deciduous forest is dominated by tall broad-leaf trees as well. We can also find mosses, shrubs and ferns. Some animals are foxes, wolves, birds,cats, and insects. The deciduous forests are also called seasonal forests because during the winter they lose their leaves because there is not enough sun light for them to do photosynthesis.
