Question

Which of the following describes how the winter season affects organisms in the tundra biome?

The cold temperatures kill most of the plants.

Plants lose their leaves to conserve energy.

The predator to prey ratio increases.

Animals not adapted to cold migrate to warmer regions.

Answer 1

I would say B or D.

Answer 2

I think losing leaves is more of a tree thing, and tundra is known for not having trees. There's definitely a lot of bird migration, though.

Answer 3

So D?

Answer 4

That would be my best guess.

Tundra is the coldest of all the biomes. Tundra comes from the Finnish word tunturi, meaning treeless plain. It is noted for its frost-molded landscapes, extremely low temperatures, little precipitation, poor nutrients, and short growing seasons. Dead organic material functions as a nutrient pool. The two major nutrients are nitrogen and phosphorus. Nitrogen is created by biological fixation, and phosphorus is created by precipitation.
Characteristics of tundra include:

Extremely cold climate
Low biotic diversity
Simple vegetation structure
Limitation of drainage
Short season of growth and reproduction
Energy and nutrients in the form of dead organic material
Large population oscillations

Answer 6

The wind blows constantly, whipping around the small plants. During the long winter months the sun barely rises
