Climate
These 2 biomes receive the least amount of yearly precipitation:
desert and tundra
Why do deciduous trees lose their leaves?
To conserve water and energy
Name an adaptation that allows an animal to deal with desert heat and sun:
Burrow underground
Nocturnal-hunt at night when the temperatures go down
Large ears release body heat
What two biomes are affected by deforestation?
deciduous forest and boreal forest
This biome is known as the "cold desert"
tundra
Type of biome located in the Pacific Northwest (U.S.):
temperate rainforest
Name an adaptation of plants in the tundra:
Grow low to the ground, grow in bunches, "hairy," dark colors, sap acts like antifreeze--to deal with cold and wind
Shallow roots--can't grow past the permafrost
Name 2 common adaptations for animals in the winter.
Hibernation- use energy from body fat while in a long, deep sleep
Migration- leave an area for a warmer location
How does desertification occur in the prairie?
Over farming and overgrazing takes away grasses and dries out the soil, if the top soil erodes away, the land can become like a desert.
This biome is home to more than half of the world's species of animals
tropical rainforest
Biome that is hot and humid:
tropical rain forest
Name an adaptation of plants in the desert:
Fleshy stems to store water
Waxy coating to prevent water loss
Grow apart to limit competition
Long, shallow roots to absorb water quickly
Name an adaptation of an animal (and why) in the TRF:
Snakes, insects, sloths, birds, frog, etc. use camouflage to blend in to their surroundings
Monkeys have long tails to travel through dense tree tops
Sloths move slowly to conserve energy
What is poaching and why is it done?
Illegal hunting
"Trophy" kills, fur and animal products, food delicacies
The biome is nicknamed the "bread basket" because of all the grain grown
prairie
Located in the temperate zone, this biome experiences seasonal temperature changes:
Deciduous froest
Many decomposers break down biotic matter quickly. The nutrients are quickly absorbed by the plants, so the nutrients do not get stored in the soil.
What is the major human impact on the tundra?
At times, this biome experiences more evaporation than precipitation, which results in little to no rainfall
desert
Explain why nighttime temperatures decrease so much at night in a desert:
There are no clouds/moisture in the air to hold in the daytime heat, so the heat escapes into the atmosphere.
Why is the soil so acidic in the boreal forest?
Decomposing needles add acid to the soil
