Land Biomes

• Biome a large area characterized by its climate
  the plants and animals that live there

3
FORESTS

• Mild temps plenty of rain
• Amount of rain temps determines which type of
  forest
• Temperate deciduous forest
• Coniferous forest
• Tropical rain forest

4
Temperate Deciduous Forests

• Deciduous means to fall off
• Lose leaves to save water during winter
• Many animals thrive
• Eat leaves, seeds, nuts, insects
• Avg. rain 29-49
• Avg. temps 43-82F

5
Coniferous Forests

• Most trees are conifers
• Needles cones
• Waxy coating (cuticle) on needles to keep from
  drying out, keeps from being damaged by cold
  temps, allows conifers to keep their leaves
  year-round
• Trees that stay green all year are called
  evergreens
• Avg. yearly rain 14-29
• Avg. temps 14-57F

6
Tropical Rain Forests

• More plants animals than any other land biome
• Canopy tree tops
• Poor soil
• Rain up to 157
• Avg. temps 68-93F

7
Grasslands

• Found on every continent but Antarctica
• Flat or gently rolling hills
• Temperate grasslands
• Few trees due to fires, drought, grazing
• Mostly grasses and flowering plants
• Large grass eaters and small seed-eating animals
• Savannas a grassland with scattered clumps of
  trees seasonal rains
• Found in Africa, India, South America

8
Deserts

• Deserts biomes that are very dry often very
  hot
• Plants grow far apart so they dont compete for
  water
• Shallow roots to get water after a rain
• Deep roots to get groundwater 100 deep
• Cactus plants store water in their fleshy limbs
• Most animals active at night

9
Tundra

• Tundra a biome that has very cold temps
  little rainfall
• Polar Tundra
• Near North South Poles
• 2nd layer of soil is always frozen (permafrost)
• Only grasses small shrubs
• Musk oxen, wolves, caribou, birds, insects are
  common
• Alpine Tundra
• Also has permafrost
• At the top of tall mountains
• Found above the tree line (where trees cannot
  grow)
• Gets plenty of sunlight precipitation
