Unit 6: Tundra & Forest Biomes (H)

What is the primary characteristic that defines the tundra biome?

• Permanently frozen ground called permafrost

• Thick coniferous forests

• Year-round warm temperatures

• Four distinct seasons

Which plants are most commonly found in the tundra?

• Tall deciduous trees

• Mosses, lichens, and low shrubs

• Palm trees and vines

• Bamboo and ferns

How have tundra animals adapted to survive in their environment?

• By developing camouflage patterns

• Through hibernation only

• With thick fur or feathers for insulation

• By living underground permanently

What is a major consequence of climate change in the tundra?

• Increased forest growth

• Formation of new permafrost

• Higher biodiversity

• Release of greenhouse gases from melting permafrost

Which forest biome experiences four distinct seasons?

• Tropical forest

• Boreal forest

• Temperate forest

• Rainforest

What characterizes the taiga (boreal forest) biome?

• Year-round warm temperatures

• Dominance of deciduous trees

• Short winters and long summers

• Dominance of coniferous trees

How do tundra plants cope with the short growing season?

• By growing extremely tall

• Through rapid growth during summer months

• By staying dormant year-round

• Through deep root systems

What is unique about tropical forests compared to other biomes?

• They experience seasonal changes

• They have limited biodiversity

• They maintain warm temperatures year-round

• They contain primarily coniferous trees

Which best describes the root systems of tundra plants?

• Deep and extensive

• Nonexistent

• Medium-depth spreading

• Shallow systems above permafrost

What effect does permafrost have on vegetation growth?

• It promotes deep root development

• It limits root growth and soil access

• It increases nutrient availability

• It extends the growing season
