Which of the following is not a species of tropical moist deciduous forests?

  1. Mahogany

  2. Sal

  3. Shisham

  4. Teak


Correct Option: A
Explanation:
Moist Deciduous Forests
They encompass a mixture of trees and grass.
They receive moderate rainfall, averaging to 100 cm to 200 cm per year with the average temperature 27-degree Celcius and the humidity level approximating to a 65-75 percent.
They grew plentifully in the Western Ghats (on the eastern sides), the Chota Nagpur plateau as well as the Shivalik mountain range.
They are also found in the Andaman and Nicobar Islands as well as parts of West Bengal and Orissa.
It is relatively easy to take advantage of these forests due to their high degree of gregariousness.
A few species of trees include teak, sal, bamboo as well as rosewood.
In this type of forest, open grass patches are often observed.

Which one among the following types of forests exhibits highest bio-diversity?

  1. Dry deciduous forest

  2. Tropical rainforest

  3. Moist deciduous forest

  4. Mangrove forest


Correct Option: B
Explanation:

Tropical rainforest,

Tropical rain forest types of forests exhibits highest bio-diversity. Tropical rainforests are known for their extreme biodiversity, posing a challenging problem in tropical ecology. A rain forest is simply an area of tall, mostly evergreen trees and a high amount of rainfall.

Moist tropical evergreen forests are found in ___________.

  1. The Shillong plateau

  2. The Siwaliks

  3. The Deccan plateau

  4. Southern India


Correct Option: A
Explanation:

The Shillong plateau,

Moist tropical evergreen forests are found in The Shillong plateau. Tropical evergreen forests in our country are found mainly in the rainy tracts of the Sahyadris and the hill regions of the Shillong plateau.

The Himalayan forests include _________.

  1. European Oak Forests

  2. Coniferous Forests

  3. Alpine Vegetation

  4. All the three


Correct Option: D
Explanation:

The Himalayas consist of a mosaic of diverse forest ecosystems and ecoregions, with different forest types suited for distinct elevation bands. Ths with the variation in the altitude, we have different types o forests in the Himalayas viz. European Oak forests, Coniferous forests and Alpine vegetation as well.

The mangrove forests are present in ________.

  1. the Eastern Ghats

  2. the Sunderbans

  3. the Western Ghats

  4. the Aravallis


Correct Option: B
Explanation:

The Sunderbans
Covering approximately 10,000 km2 the Sundarbans in the Northern Bay of Bengal is the largest contiguous mangrove forest on earth. Mangroves forests are highly productive and diverse ecosystems, providing a wide range of direct ecosystem services for resident populations. In addition, mangroves function as a buffer against frequently occurring cyclones; helping to protect local settlements including the two most populous cities of the world, Kolkata, and Dhaka, against their worst effects. While large tracts of the Indian Sundarbans were cleared, drained and reclaimed for cultivation during the British colonial era, the remaining parts have been under various protection regimes since the 1970s, primarily to protect the remaining population of Bengal tigers (Panthera tigris ssp. Tigris). 

Which of the following regions has almost all prevalent types of natural vegetation in India?

  1. The Coastal Plains

  2. The Deccan Plateau

  3. The Himalayas

  4. The Ganga Plain


Correct Option: C

Assertion (A): The Himalayan ranges show change in vegetation from tropical to Tundra.
Reason (R): In mountainous area with increase in altitude there is corresponding decrease in temperature, which leads to change in vegetation types.
Select the correct option from the given alternatives.

  1. Both (A) and (R) are true and (R) explains (A)

  2. Both (A..) and (R) are true but (R) does not explain (A)

  3. (A) is true and (R) is false

  4. (A) is false and (R) is true


Correct Option: A
Explanation:

The character and extent of vegetation are mainly determined by temperature along with the humidity in the air, precipitation and soil. On the slopes of Himalayas and the hills of Peninsula above the height of 915 metres, the fall in the temperature affects the types of vegetation and its growth, and changes it from tropical to subtropical temperature. So in the mountainous area with the increase in altitude there is corresponding decrease in temperature, which leads to change in vegetation types. 

How much of the world's land area is tropical rainforest? 

  1. 2%

  2. 5%

  3. 7%

  4. 9%


Correct Option: C
Explanation:

Tropical rainforests are the forests consisting of evergreen trees with green foliage throughout year. They constitute 6 to 7% of earth’s land surface. Such forest give shelter to 50% of world’s species.

The greatest diversity of animal and plant species occurs in ________________.

  1. temperature deciduous forests

  2. tropical moist forests

  3. heavily polluted rivers

  4. deserts and savannas


Correct Option: B
Explanation:
 Tropical rainforests are areas of extremely high biodiversity compared to other ecosystems. Biologists estimate that tropical rainforests contain about 50% of the world's terrestrial plant and animal species, yet they encompass only about 6% of the world's land area.

My stem is succulent, my leaves are mostly thick.
In which category of the following vegetation type I am largely found?

  1. Tropical deciduous forest

  2. Montane forest

  3. Tropical thorn forest and scrubs

  4. Mangrove forest


Correct Option: C
Explanation:

Stems are succulent and leaves are mostly thick. This means that the vegetation is found in the area of Tropical thorn forests and scrubs. This is an adaptation which turn leaves thick and succulent to prevent water loss from transpiration.
