  1. The main terrestrial ecosystems Modified from C.Hill 10/26/2009

  2. Tundra • Permafrost, continuously frozen ground • Large mammals with good insulation that include: musk oxen and caribou • Smaller animals include: lemmings, arctic fox, and snowy owl.

  3. Tundra • Northernmost limits of plant growth • High altitudes • Little precipitation • Extremely cold winter air temperature • Alaska, Canada, Scandinavia, and Russia

  4. Taiga: Coniferous Forests • Cone-bearers • Spruce, Pine, Fir, and Hemlock • Harsh winters, short summers • Thin, acidic soil

  5. Taiga: Coniferous Forests Taiga, themost extensive, stretchs across North America and Eurasiareaching the southern border of the artic tundra.

  6. Deciduous Forests • Sufficient moisture • Large trees • Oak, Hickory, Beech, and Maple  • Experience each season

  7. Deciduous Forests • Dominates most of the eastern United States • Soil rich in inorganic and organic nutrients • Support speices such as: arthropods, birds, small mammals, bobcats, foxes, black bears, and mountain lions

  8. Mediterranean forest • Dense, spiny shrubs • Tough evergreen leaves • Mild, rainy winters • Long, hot, dry summers

  9. Mediterranean forest • Require occasional fires for long-term maintenance • Plants regenerate quickly • Animal browsers such as: deer, fruit-eating birds, seed-eating rodents, lizards, and snakes

  10. Deserts • Sparse rainfall • Rapid evaporation • No perennial vegetation • Scattered shrubs and cacti

  11. Deserts • Desert plants and animals adapt to drought and extreme temperatures • Only active during cooler nights • Conserve water and seed-eaters such as: ants, birds, rodents, lizards, snakes and hawks

  12. Savanna • Dominated by grasses and scattered trees • Frequent fires • Rapid growing grass, good food source

  13. Savanna • tropics in central South America  • central and South Africa; home to giraffes, zebras, antelopes, baboons, lions, and cheetahs.

  14. Tropical Rain Forest • Rain is abundant • Poor soil • Large trees • Closed canopy

  15. Tropical Rain Forest • Found in very humid equatorial areas such as: • Indonesia • Amazon River basin

  16. Say the names of the following ecosystems

  17. MARINE BIOMES NERITIC ZONE PELAGIC ZONE APHOTIC EUPHOTIC

  18. MARINE BIOMES Which beings live in each zone? 1 2 3

  19. Plankton, nekton and benthos are the three groups into which aquatic living beings may be divided.

  20. MARINE BIOMES Animal or vegetal beings? Planktonic, benthic or nektonic beings? 1 2 3
