Biomes

Chapter 6-2.3: Cold Biomes

Chaparral

• Animal adaptations

  • Many animals are nocturnal

  • Burrowing animals avoid fire and heat

  • Long limbs allow for temperature regulation

Multiple Choice

What was the purpose of setting the hillsides ablaze at the UC Hopland Research and Extension Center?

• 100%

Multiple Choice

Areas defined by their geographical location and ecological similarity are called?

• ecozones
• biotopes
• biomes
• biodomes

Multiple Choice

• Deciduous Forest

• Grassland

Multiple Choice

Chaparral is all of the following except

• very wet

• moderately dry

• coastal

• very little rain in summer

Multiple Choice

Characteristics of this biome include: warm year round, large herbivores and predators, drought resistant plants, animals give birth during the rainy season.

• tropical rainforest

• savanna

• desert

• tundra

Multiple Choice

This biome has trees that lose their leafs in the winter, experiences four seasons, and gets enough rain to support the growth of trees.

• Rain forest

• Taiga

• Grassland

• Deciduous forest

Lesson Objectives

• Compare and Contrast the biomes that exist in colder climates

Taiga (The Boreal Forest)

• Stretches across the northern regions of the Earth

  • Canada, Alaska, Russia, and Scandinavia

• Regions of cool temperatures and low dry seasons

  • Long cold winters with short cool summers

• Soil conditions are low in nutrients

  • some of the soil is acidic

• Has an overall low species diversity

Taiga (The Boreal Forest)

• Plant Adaptations

  • Trees are coniferous

    • cones can shed snow without damaging seeds

  • Most plants have a Symbiotic relationship with fungi that allow them to access nutrients

Taiga (The Boreal Forest)

• Animal Adaptations

  • Most animals feed, breed, and reproduce during the short summers

  • Thick insulation and fat to conserve heat

  • Small Extremities

  • Some change color to blend into the snow during the winter

  • Many birds migrate here during the summer to eat the insects that come out during that time

Multiple Choice

What is another name for the taiga biome?

• Tundra

• Boreal Forest

• Savanna

• Desert

Multiple Choice

What type of trees are found in the taiga biome?

• Oak and Maple

• Palm and Bamboo

• Spruce and Fir

• Birch and Willow

Multiple Choice

Which of the following animals can be found in the taiga biome?

• Lion and Giraffe

• Kangaroo and Koala

• Moose and Reindeer

• Elephant and Rhino

Multiple Choice

What is the main reason for the limited range of animals in the taiga biome?

• Lack of food sources

• Extreme heat

• Excessive rainfall

• Strong winds

Tundra

• Near the North Pole

  • Highest latitudes of Alaska, Canada, Scandinavia, and Russia

• As dry as deserts, but much colder

  • Long, freezing, dark winters and short cold summers

• Harsh winds and nutrient poor soils limit plant growth

  • the only vegetation is short shrubs and lichens

    • Have a symbiotic relationship with bacteria

Tundra

• Permafrost: underground soil that is frozen year-round

• During summers, some of the surface ice melts and creates conditions ideal for insects

  • Brings migrating animals for the summer

• Only a few species live here year-round.

  • Polar Bears

  • Musk Oxen

Multiple Choice

What are tundras?

• Regions with extreme heat and high rainfall

• Treeless regions with extreme cold and low rainfall

• Regions with dense forests and moderate temperatures

• Regions with sandy deserts and high winds

Multiple Choice

What prevents trees from taking root in the arctic tundra?

• Extreme heat

• High altitude

• Permafrost

• Heavy rainfall

Multiple Choice

How is global warming affecting the arctic tundra?

• Increasing the number of trees

• Decreasing the wildlife population

• Melting the permafrost and releasing carbon

• Reducing the temperature

Polar Ice

• Technically not considered its biome

• Extends from the tundra to the poles of

• No solid ground, just ice

• Most life lives int the water

• Animal adaptations

  • Antifreeze proteins to prevent blood from freezing

  • Blubber and fat

  • Thick Fur

Mountains

• Technically not considered a unique biome

• Experience changes in communities and conditions as you climb higher
