• Deciduous Latin for to fall off
• Trees shed leaves to save water during the dry
  season.
• Animals include bears, deer, raccoons, fox,
  snakes, and woodpeckers.

11

• Most animals live in the canopy.
• Canopy treetops
• 1,400 birds live in the canopy

Temperate Grasslands

• Plants grasses and other flowering plants
• Have few trees
• Animals include prairie dogs, mice, and bison.

• Summer 86 degrees F
• Winter 32 degrees F

16
Savannas

• During dry season, grasses dry out and turn
  yellow but survive because of the deep roots.

Deserts

• Very dry and very hot
• Plants grow far apart so they dont have to
  compete for water.
• Animals are mostly nocturnal (active at night)
• Cactuses, spadefoot toad, desert tortoises
• Rainfall less than 25 cm
• Summer 100 degrees F
• Winter 45 degrees F

Spadefoot Toad

Tundra

• Polar Tundra
• Alpine Tundra
• Tundra biome that has very cold temperatures and
  little rainfall- can be called a cold desert
• NO TREES!
• Covers 1/5th of the world
• Rainfall 30-50 cm
• Summer 54 degrees F
• Winter -15 degrees F

20
Polar Tundra

• Found near North and South Poles
• Layer of soil beneath surface (permafrost) is
  frozen all the time.
• Shallow rooted plants grasses and shrubs
• Animals insects, birds, wolves, caribou

21
Alpine Tundra

• Like Polar Tundra
• Found at top of tall mountains and above tree
  line.
• Tree line above this line, trees cannot grow.
• Plenty of sunlight and precipitation

22
The lighter green color is above the tree line.
