Question

Why is the tundra dominated by short shrubs and low lying plants?

Group of answer choices

The frozen ground does not allow roots for large trees to grow.

The lack of sunlight prevents green plants from growing tall.

The cold temperatures force plants to remain close to the warmth of the ground.

The high winds blow over any trees above a certain height.

Answer 1

The frozen ground does not allow roots for large trees to grow

Explanation: characteristic of *severe cold climate regions* *especially treeless artic regions* and high mountain tops. Plant life must adapt itself to a *short growing season(e.g,shrubs and low lying plants adapt themselves to short growing season)* of about 60 days and to a soil that remain frozen for most of the year. Most tundra regions are covered with bogs, marshes, ponds and a spongy mat of decayed vegetation, although high tundras may be covered with only lichens and grasses. Vegetation of dwarf woody plants, grasses, sedges and lichens may be quite profuse in tundra despite the thin soil and short growing season.

Therefore, large trees cannot allow roots for large trees to grow in frozen ground but short shrubs and low lying plants can,to an extent .
