Why is there limited vegetation in the tundra?
a. the soil is frozen and devoid of nutrients.
b. there is frequent flooding and the soil is nutrient-poor.
c. there is frequent flooding and the soil is nutrient-rich.
d. the soil is frozen and contains pockets rich in nutrients.

A. The soil is frozen and devoid of nutrients.  

Tundra biomes are the coldest biomes on Earth. They are found in regions where vegetation growth is hindered by the low temperatures, little precipitation, short growing seasons. The soils in these regions remain in permafrost condition and poor in nutrient content. Hence, the soil cannot support the growth of vegetation in the tundra biome.  

There is limited vegetation in the tundra state because the soil is frozen and devoid of nutrient (A).

Further Explanation:

Tundra biome is present in the northern hemisphere. The temperature of tundra biome is around -38 to -50C .tundra  is a treeless mountain.

Tundra has a very low temperature which leads to the freezing of the water present.

As the water freeze, the availability of water in liquid form scars in tundra.the soil remain in frozen state which leads to non-availability of it for vegetation or agriculture.

Because of the low and harsh climate growth rate of plant are low and mostly small plants grow like dwarf shrubs, grasses, mosses, lichens.

So, tundra biome soil is unfit for growing plant and vegetation is limited in the tundra biome.

Characteristics of tundra biomes-

      •   Extremely cold climate.

      •   Biotic diversity is very low.

      •   vegetation structure is simple.

      •   Restriction of drainage

      •  Growth and reproduction are for a very short season.

      •   Energy and nutrients are present in the form of dead

          organic material.

the correct answer is option b

behavioral response need communication and thus co-ordination at several levels such as interaction among cells, organ system and the entire organism.

behavioral response produces both internal and environmental stimulus.
