BIOMES WebQuest  Biomes: major communities of organisms that have a characteristic appearance and are distributed over a wide area defined largely by vegetation and regional variations in climate o Ex: tropical rainforest, savanna, desert, temperate grassland/deciduous forest/evergreen forest, taiga, and tundra **Moisture and temperature determine a biome  Tropical Rainforest – 140-450 cm of rain per year and contain over half of the earth’s plants and animals; soil is not nutrient-rich, most nutrients from plants  Savanna – grasslands that border the tropics and receive 75-125 cm of rain per year; alternates rainy and dry seasons; inhabited by huge herds of grazing animals that migrate during season changes  Desert – less than 25 cm of rain per year; vegetation is sparse, and survival depends on water conservation  Temperate Grassland – found halfway between equator and the poles; characterized by fertile soil  Temperate Deciduous Forest – occur in regions with warm summers, cool winters, and plenty of rain; dominant species of trees include: oak, maple, ash, and hickory  Temperate Evergreen Forest – occurs in regions where winters are cold and there is a strong, seasonal dry period  Taiga – great ring of northern forests with coniferous trees; one of the largest ecosystems on earth; long, cold winters and most of the limited precipitation falling in the summer  Tundra – far north above taiga where few trees grow; open, windswept, and often boggy grassland; small and confined trees to regions near lakes and streams; large grazing animals (reindeer and caribou) as well as carnivores (wolves and foxes) live in these areas
