An interactive model "Biomes"" demonstrates a variability of biomes (major communities of plants, animals, and microorganisms that occur over wide geographical areas and have distinct characteristics): polar ice, tundra, taiga, temperate mixed and deciduous forests, tropical rainforest, chaparral, temperate grassland, savanna, semidesert, desert, mountain zones. You may select the region from tight list located in lower part of the model. To do this press the "Up" or "Down" buttons until a name of required area appears in the line of the list. Another way of the biome selection is to put a cursor on that place of the map of Earth which corresponds to the selected biome. After selection of the biome the whole number of areas that corresponds to this kind of area will be marked. Image in the lower part of the model would present the typical landscapes of the selected biome.
