Transcript of Biomes

• Rely on plants and other prey to survive
• Sometimes animals like caribou have to eat tree bark because other plants die because of the cold
• Have thicker fat and fur because they need to stay warm
• Mountainous
• rugged and hilly
• low-nutrient soil
• icy and snowy ground
• Not all areas have snow.

Biomes: Tundra vs. Rainforest
• Cold, average of -30 degrees Fahrenheit in North Pole
• very dry
• Lots of snowfall
• the ground is often icy.
• Tropical Climate
• Temperature rarely go above 93 degrees or below 63 degrees.
•Very humid, about 77% to 88%
• adaptable
• don't need many nutrients; aren't many in the soil
• they must shield themselves from harsh winds to survive
• trees have thick bark for protection

•Some animals must adapt to the extremely humid climate beneath the lower canopy.
•Animals have thin skin and fur/feathers that is not a heavy coat.
•Most animals have a diet heavily based on the fruits that are available in a rainforest.
•The forest floor itself if not very thick with vegetation. Hardly any sunlight reaches this part.
•Most trees have smooth thin bark since they don’t have to deal with cold temperatures.

•The air beneath the lower canopy is VERY humid. So, leaves release water through the pores of their leaves.
•Trees grow straight up to reach the sunlight. Branches don’t span more than 100 feet because there isn’t much sunlight.
Trees have smooth thin bark since they don’t have to deal with cold temperatures.
Plants have adapted to shake rain quickly off because of all of the rain so branches don’t get weighed down and break.Leaves are very large so they absorb as much sunlight as possible.

• There is a lot of rain!!!!!!
• There is about 60 to 250 cm of rain each year.
• There is a lot of snowfall
• There is about 6-10 inches of snow every year.

• Clouds block out the sun in a tundra while the canopy blocks out the sun in a rainforest.
• Moss and lichen
•Lots of precipitation.
•The plants in both biomes use their own techniques to stay alive in their area, despite difficulties.
•carnivores and omnivores
