Which of the following describes how the winter season affects organisms in the tundra biome?
a. the cold temperatures kill most of the plants.
b. plants increase the size of their leaves to absorb sunlight.
c. the predator to prey ratio increases.
d. animals not adapted to cold migrate to warmer regions.

    The right answer to this question is option D. Animals not adapted to cold migrate to warmer regions.

Explanation:

     We can easily confirm this option by checking out birds, they're a very good example for that because they have a very good advantage through other organisms, they can fly, and by doing that, it's easy for them to go onto another biome. If a specific species of bird need hot weather to grab its food, there's no need for it at a cold spot, so this bird will probably search for a warmer place where there's enough food for it to survive.
