Natural Vegetation and Habitats Questions

Multiple choice

Biomes are identified on the basis of

  1. cities

  2. plants

  3. states

  4. rocks

  5. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Biomes are large ecological areas on the earth's surface, with fauna and flora adapting to their environment. They are primarily identified by the types of vegetation (plants) present.

Multiple choice

Consider the following:

  1. Presence of deciduous forests
  2. Presence of evergreen coniferous forests
  3. Presence of mixed forests

Which of the following climatic zones has the above mentioned characteristics?

  1. Warm Temperate Zone

  2. Cool Temperate Zone

  3. Alpine Zone

  4. Equatorial Zone
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In geography, temperate or tepid latitudes of the globe lie between the tropics and the polar regions. In a very broad sense, temperate climate also includes a subtropical climate, variants: subtropical semi-desert/desert, humid subtropical, oceanic subtropical and Mediterranean climate. However, a typical temperate climate is one of the four climate zones in the world, besides polar regions (subarctic climate, arctic climate, tundra climate, ice cap climate) and the sub-tropics, tropics. The forest types found in cool temperate regions are: Deciduous forests, Evergreen coniferous forests and Mixed forests.

Multiple choice

Arrange the following Himalayan vegetation type in the descending order on the basis of the altitude beginning from the highest.

  1. Coniferous forests
  2. Alpine vegetation
  3. Tropical forests
  4. Evergreen forests

Select the correct answer using the code given below.

  1. 1 – 2 – 4 – 3

  2. 1 – 2 – 3 – 4

  3. 2 – 1 – 4 – 3

  4. 2 – 1 – 3 – 4
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The descending order of altitude for Himalayan vegetation is: Alpine vegetation (highest), Coniferous forests, Evergreen forests, and Tropical forests (lowest). Therefore, the sequence is 2-1-4-3.

Multiple choice

Consider the following statements.

  1. The natural vegetation of tropical monsoon lands depends upon the amount of the annual rainfall.
  2. In tropical monsoon forests, trees are normally deciduous because of the marked dry period.

Which of the statements given above is/are correct?

  1. Only 1

  2. Only 2

  3. Both 1 and 2

  4. Neither 1 nor 2
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Statement 1 is correct: One of the principal deciding factors of the type of natural vegetation of a region is the rainfall of that region. This factor becomes more crucial in the case of tropical monsoon lands. Statement 2 is also correct: Monsoons lands are characterised by marked dry period. In such dry periods, trees shed their leaves. Hence, monsoon lands are covered with deciduous trees.

Multiple choice

Which of the following types of forests is the most widespread in India?

  1. Tropical evergreen forests

  2. Tropical deciduous forests

  3. Tropical thorn forests

  4. Montane forests

  5. Littoral forests
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

This is the correct answer. Tropical deciduous forests are the most widespread in India. They are also called the monsoon forests. They spread over regions which receive rainfall between 70-200 cm.

Multiple choice

Which of the following statements is/are correct?

a. Tropical deciduous forests are found in warm and humid areas with an annual precipitation of over 200 cm and mean annual temperature above 22oC. b. Tropical evergreen forests are well stratified, with layers closer to the ground and are covered with shrubs and creepers. c. Semi evergreen forests have a mixture of evergreen and moist deciduous trees.
