Presentation Transcript

  1. Biomes A group of land ecosystems with similar climates and organisms.

  2. Types of Biomes Desert Grasslands Temperate Forests/Deciduous Forest Tropical Forests Taiga/Coniferous Forest/Boreal Forest Aquatic: Oceanic and Fresh Water Tundra

  3. Desert Biome • Middle latitudes • Very little precipitation: less that 25 cm/year • Can be hot or cold • Vegetation: cacti, desert plants • Lizards, snakes, kangaroo rat, owls, foxes, javelinas, coyotes

  4. Grasslands • Found in the middle latitudes • Moderate rainfall: 50-90 cm per year • Grasses but few forests • Periodic wildfires • Grazing animals: bison, horses, gazelles, zebras, wolves, tigers and lions.

  5. Temperate/Deciduous Forests • Forest biome • Short winters (2 months) • 75 to 150 cm of rainfall per year • Broad leaf trees • Most trees loose leaves and go dormant in winter • Variety of animals: squirrels, deer, raccoons, wolves, foxes, bobcats, many insects

  6. Tropical/Rain Forests • Near the equator • Warm to hot temperatures • Abundant rainfall: 250 to 400 cm per year • Many plants, animals and insects • Monkeys, birds, insects, snakes

  7. Boreal/Coniferous Forests (Taiga) • Very cold • Coniferous trees (Pine trees) • More rain than Tundra: 30-60 cm per year • Deer, elk, beavers, bears, wolves, owls

  8. Aquatic • Freshwater Biomes: • Rivers & streams • Lakes & ponds • Estuaries (mixture of fresh and saltwater) • Marine Biomes: • Coastal • Open ocean • Deep ocean

  9. Tundra • Very cold and dry • -50 degrees F • less than 25 cm of rain per year • Northern-most part of the globe: Arctic • Owls, bears, small rodents, white fox, caribou, oxen
