3. Rainforest Biome Rainforest video
Make up about 7% of Earth’s surface, yet contain more than 50% of all plant and animal species on the planet
Warm and wet year-round, never below about 75 degrees fahrenheit
78 inches to 354 inches of rain annually
Three major layers:
Canopy: Top layer, where the thick leaves and tall trees form an “umbrella” over the forest
Understory: Shorter trees, bushes, and ferns, and the animals that live there.
Forest floor: Very little sunlight reaches the forest floor. Bugs, insects, and snakes make this place their home.

5. Deciduous (Temperate) Forest
Average temperatures and average amount of rainfall
Exists on every continent, except Antarctica and Africa
Trees shed their leaves each year
Multiple seasons occur due to the amount of sunlight
Several layers of plants can be found here
Tall trees (which create a canopy) let light reach the bottom where bushes and smaller trees grow (unlike in the rainforest)
These plants provide a variety of habitats for animal life

7. Taiga Biome (boreal forest)
- One of the 3 forest biomes, and has the largest total land area.
- Coniferous, evergreen trees have thin needles that have adapted to collect rain
- Total rain is only between 12 to 30 inches a year
- 6 month winters that can average -60 degrees fahrenheit
-Short, hot summers; because it’s so far north, the sun hits it directly
- Animals have adapted with thick fur to survive the winters. - Other animals will hibernate or migrate to stay safe.
- Has many bogs- swampy pools of water and dead plants that have collected over time.

9. Tundra Biome Tundra Biome
Three types of Tundra: Arctic tundra, Antarctic tundra, and Alpine tundra.
Arctic tundra has many flat plains with no trees
Formed from retreating glaciers
Covered in ice and snow for seven to eight months of the year
Winters can reach -90 degrees, Summer temperatures rarely hit 50 degrees
Permafrost layer beneath the surface layer always remains frozen
In summer, the surface layer can melt, creating ponds and wet ground that will allow certain plants to grow.
Arctic and Antarctic tundras are cold deserts with less than 10 inches of rain annually.
Alpine tundras exist on mountaintops all over the world.
High winds and heavy snowfall

11. Grasslands/Savanna Biome video Grasslands, Savanna, Prairie
also known as Savanna(Africa) or Prairies(North America)
mainly have grasses growing and few trees
little rain
long slender leaves allow little water loss in plants
Breadbasket of the world because of the wheat and grain that grows

13. Desert Biome video Deserts soil and air are dry little rain
sun shines most of the time
temperature hot in day (summer) and can be freezing at night (winter)
few plants: cactus and bushes
snakes, lizards, few mammals like rabbits
