  2. Land Biomes! Around the World! Earth’s Land Biomes!

  3. Temperate Deciduous Forest • Temperate = moderate temperature, not extreme • Deciduous = “falling off” in Latin. • Adaptations: Tree leaves fall off in winter to save water, trees have thick bark to protect against cold winters.

  4. Coniferous Forest • Conifers = pinetrees! • Adaptation: Trees have needles with a waxy coating. Waxy coating keeps trees from drying out, protects needles from winter damage, and allow trees to shed snow more easily than deciduous tree leaves

  5. Tropical Rain Forest • Has most biodiversity – 100 different kind of trees in one quarter of a football field! • Most animals live in canopy (treetops) • Adaptations: Trees’ roots grow above ground for extra support in soil • Adaptation: Some plants grow on others to reach the sunlight!

  6. Temperate Grassland • Few to no trees! Not enough water, too many fires and animals eat everything. • Adaptation: Prairie shrubs easily resprout after fire. • Adaptation: Some prairie trees have thick bark to protect against fire

  7. Savanna • Like a prairie, but with some scattered trees. • Adaptation: In dry season, tops of grasses turn yellow and die, but grasses’ deep roots survive many months without water!

  8. Desert • Is very hot and dry, but has many plants and animals. • Adaptation: Most animals are active at night when it’s cooler • Adaptation: Plants grow far apart so they don’t compete with each other for water. • Adaptation: Cacti have fleshy stems and leaves that store water and prevent water loss.

  9. Tundra • Is very cold and has little rainfall. • Plants are very small due to lack of nutrients and roots cannot penetrate permafrost • Adaptations: Plants grow close together to keep warmer • Adaptation: Some plants have hair to keep warm • POLAR vs. ALPINE
