What type of climate does the taiga biome have?

• Warm summers and cold winters

• Hot and dry all year

• Mild and rainy all year

• Cold summers and warm winters

Answer explanation

The taiga biome is characterized by warm summers and cold winters, which supports coniferous forests. This climate allows for distinct seasonal changes, unlike the other options which do not accurately describe the taiga.

What adaptation helps evergreen trees in the taiga survive the winter?

• Waxy leaves and drooping limbs

• Deep roots and broad leaves

• Bright flowers and tall stems

• Thick bark and shallow roots

Answer explanation

Evergreen trees in the taiga have waxy leaves that reduce water loss and drooping limbs that help shed snow, preventing branch breakage. These adaptations are crucial for surviving harsh winter conditions.

How do plants in the tundra adapt to the cold conditions?

• By growing low to the ground and being dark-colored

• By having large leaves and tall stems

• By storing water in thick stems

• By shedding leaves in winter

Answer explanation

Plants in the tundra adapt to cold by growing low to the ground, which helps them avoid harsh winds and conserve heat. Being dark-colored also aids in absorbing more sunlight, crucial for survival in this extreme environment.
