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 correct answer is D. Animals not adapted to cold migrate to warmer regions, because suppose that the cold temperatures kill most of the plants, so if they can die why they select that place to live? The option B is not logical because this require long time to evolve this characteristic and the option C has more logic but it still not enough, because if the temperatures are colder more animals can die. I hope this help.

hello there the answer is d
