Cold Environment Adaptations Flashcards

All 6 cards in this deck

Why do tundra plants have shallow root systems?

Only the thin active layer thaws — permafrost below blocks deeper roots.

Why do tundra plants grow low to the ground in clumps?

To shelter from strong, cold winds and keep warmth near the soil.

Give one plant adaptation to the very short growing season in the tundra.

Plants are dormant rather than dying off, and many use underground runners or bulbs instead of seeds so they grow as soon as light returns.

True or false? The Arctic fox keeps white fur all year round.

False. Its coat changes with the seasons – white in winter for camouflage in snow, brown or grey in summer.

How do many cold-environment animals stay warm?

They are insulated by a thick layer of fat (blubber) or dense fur, which traps body heat.

Give two ways animals survive the long winter in cold environments without facing the worst conditions.

Hibernating through the coldest months to save energy, or migrating to warmer areas with more food and returning in summer.
