More on jungle soils. The tropical rain forest exceeds all the other biomes in the diversity of its animals as well as plants. Their existence depends on the fact that it never freezes, and they often escape the fires that periodically sweep the Everglades. This biome occupies the eastern half of the United States and a large portion of Europe. The number of different species is far more limited than in the jungle.
Large stands dominated by a single species are common.
Deer, raccoons, and salamanders are characteristic inhabitants. During the growing season, this biome can be quite productive in both natural and agricultural ecosystems. The taiga is named after the biome in Russia. It is a land dominated by conifers , especially spruces and firs. It is dotted with lakes, bogs, and marshes.
