The correct answer is Tropical Deciduous forest.

Key Points

• India has the following types of vegetation:
  • Tropical Evergreen Forest
  • Tropical Deciduous Forest
  • Tropical Thorn Forest
  • Montane Forest
  • Mangrove Forest
• Tropical Deciduous forest is the most widespread forest in India.
• They are also called monsoon forests and spread over regions having 200cm and 70 cm of rainfall.
• Trees of this forest shed their leaves for about six to eight weeks in dry season.
• Teak is the most dominant species of this forest.
• Bamboo, sal, sheesham, sandalwood, khair, kusum, arjun and mulberry are other important species.

 Thus, we can say that the Tropical Deciduous forest is the most widespread forest in India.

The correct answer is Subtropical evergreen.

Key Points

• The vegetation of Mount Abu consists of many plants that are similar to the subtropical region of the Himalayas.
• Around Mount Abu, they are well represented between 700 to 800 m altitudes.
• The other vegetation of Mount Abu supports dry deciduous, semi-deciduous and evergreen species, which changes with the increase in altitude.

Additional Information

• Tropical thorn forests are found in arid and semi-arid regions of western Rajasthan, namely Jodhpur, Pali, Jalore, Barmer, Nagaur, Churu, Bikaner etc.
• Tropical Dry Deciduous (Dhol) Forests are mostly found in the northern and eastern slopes of Aravalli ranges, mostly in Alwar, Bharatpur and Dholpur districts, which are covered with this type of forests.

The correct answer is Lose their leaves in winter.

Key Points

• Deciduous trees shed their leaves during winter or dry seasons to conserve water and energy.
• The shedding of leaves helps prevent water loss through transpiration, especially when water is scarce or frozen.
• During this period, the trees enter a state of dormancy, slowing down their metabolic activities.
• The process is triggered by changes in environmental factors such as shorter daylight hours and cooler temperatures.
• Examples of deciduous trees include oak, maple, birch, and elm.

Additional Information

• Transpiration: The process by which plants lose water vapor through small openings called stomata in their leaves.
• Dormancy: A survival mechanism in which plants temporarily stop growing and conserve resources during unfavorable conditions.
• Chlorophyll Breakdown: As leaves prepare to fall, chlorophyll breaks down, revealing other pigments like carotenoids and anthocyanins, which cause the vibrant autumn colors.
• Abscission Layer: A specialized layer of cells forms at the base of the leaf stem, facilitating leaf detachment without damaging the tree.
• Evergreen Trees: In contrast, evergreen trees like pines and spruces retain their leaves year-round and adapt differently to conserve water.

The correct answer is Europe.

Key Points

• Europe has the largest forest cover among the continents of the world.
• In 2005, there were about one billion hectares of forest in Europe, and by 2020 this area had increased slightly to about 1.02 billion hectares.
• Thus, the continent has a forest cover of 1.42 hectares per capita.
• The Russian Federation accounts for 81% of the continent’s forest area.
• The forest area of the continent has exhibited a steady rise of 0.08% annually.
• Over two-thirds of Europe’s forest cover is, however, semi-natural.
• Northern and eastern Europe has larger areas of virgin forest cover than the western parts of the continent.

The correct answer is Tropical Deciduous Forests.

Key Points

Tropical Deciduous Forests:

• TROPICAL DRY DECIDUOUS FORESTS.
  • Found in the areas having rainfall between 70-100cm.
  • Present in rainier areas of the peninsula and the plains of Uttar Pradesh and Bihar.
  • During Dry seasons, Trees shed their leaves completely and the forest appears like a Grassland.
  • Main species of Tropical Dry Deciduous Forests: Khair, Tendu, Palas, axlewood, bel, etc.

Additional Information

Tropical Evergreen Forests:

• These forests are restricted to heavy rainfall areas of the Western Ghats and the island groups of Lakshadweep, Andaman, and Nicobar, upper parts of Assam, and Tamil Nadu coast.
• They are at their best in areas having more than 200 cm of rainfall with a short dry season.
• The trees reach great heights up to 60 meters or even above.
• Since the region is warm and wet throughout the year, it has luxuriant vegetation of all kinds.
• The trees, shrubs, and creepers give it a multilayered structure.
• There is no definite time for trees to shed their leaves.
• As such, these forests appear green all the year-round

The correct answer is Tundra Forest.

Key Points

• Mosses and lichens are most commonly found in the Tundra Forest.
• Key reasons include:
  • Cold Climate: The tundra is characterized by very cold temperatures.
    • Mosses and lichens can survive these extreme conditions as they are adapted to cold climates.
  • Short Growing Season: The growing season in the tundra is very short, but mosses and lichens can grow and reproduce quickly during this period.
  • Low-Nutrient Soil: The tundra has low-nutrient soil, which is suitable for mosses and lichens, as they can grow on poor substrates.
  • Limited Competition: In the harsh conditions of the tundra, there are fewer competing species, which allows mosses and lichens to thrive.
  • Tolerance to Drought and Frost: Mosses and lichens have a high tolerance to drought and frost, which makes them suitable for the tundra environment.
