Question

which would be an adaptation for living in the tundra?
o tunnel shaped leaves to help water runoff
deep roots to go into the permafrost
hibernation to lower metabolism in the winter
o large ears to release heat

Explanation:

• Tunnel - shaped leaves for water runoff: Tundra has low precipitation (not heavy rainfall like in rain - forest where water runoff leaves are useful).
• Deep roots into permafrost: Permafrost is permanently frozen, so roots cannot go deep into it.
• Hibernation to lower metabolism: Tundra has harsh winters. Hibernation helps animals conserve energy during the cold, food - scarce winter months.
• Large ears to release heat: Tundra is cold, and animals need to conserve heat, not release it. Large ears for heat release are more common in hot climates.

Answer:

hibernation to lower metabolism in the winter
