Adaptions

• Why are cold environments difficult to survive in?

  Because they present harsh conditions that challenge survival even for well-equipped explorers
• What adaptations do plants have to survive in tundra environments?

  • Dormancy during cold winters
  • Low-growing and round shape for wind protection
  • Shallow roots due to permafrost
  • Small leaves to limit moisture loss
  • Short growing season of 50-60 days
  • Reproduction through underground runners or bulbs
• What is the typical growing season for plants in tundra environments?

  50-60 days
• How do animals in cold environments conserve energy?

  By being well-insulated with thick fur or blubber
• How long do Arctic ground squirrels hibernate?

  1. 8 months
• What do reindeer eat during the winter?

  Lichens
• How does migration help birds in cold environments?

  It allows them to find warmer areas with more food during winter
• What is a common adaptation of animals for camouflage in snowy environments?

  Growing white winter coats
• What is the impact of low biodiversity in cold environments?

  • Fewer species of plants and animals
  • Changes in one species can affect dependent species
  • Example: Lemming population changes affect Arctic foxes
• How is global warming affecting species in cold environments?

  It causes some species to move towards the poles in response to temperature rises
• What risk do species already adapted to polar environments face due to climate change?

  They are at risk of decline or extinction if polar areas warm too much
• What should students focus on when studying cold environments?

  • How plants and animals adapt to cold conditions
  • The importance of biodiversity in these environments
