• Also, called Monsoon Forests.
• They are found in the regions having rainfall between 70-200cm.
• They shed their leaves for about six to eight weeks in dry summer.
• Tropical Deciduous Forests are further classified into two types of forests on the basis of rainfall- Tropical Moist Deciduous Forests and Tropical Dry Deciduous Forests.
• TROPICAL MOIST DECIDUOUS FORESTS:
  • Present in the areas having rainfall between 100-200cm.
  • Found in eastern slopes of Western Ghats, foothills of the Himalayas in the North-eastern States and Odisha.
  • Main Species of Tropical Moist Deciduous Forests: Teak, Sal, Sheshum, amla, Kusum, mahua, Sandalwood, etc.
• TROPICAL DRY DECIDUOUS FORESTS.
  • Found in the areas having rainfall between 70-100cm.

  • 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 correct answer is Africa.

Key Points

• The savanna and velds make up the central part of Africa.
• In Africa, the grasslands are called savannas and range from desert grass plains to those of trees and bushes.
• The veldt, typical of the interior of South Africa, is a vast area of treeless grassland.
• Some of the countries with savannahs are Kenya, Tanzania, Zambia, Chad, Sudan, Ethiopia, Somalia, Zimbabwe, Mozambique, Botswana, and South Africa.

Additional Information

• Important grasslands in the world are

  Steppe	Europe and North Asia
  Pustaz	Hungary
  Prairies	USA
  Pampas	Argentina
  Downs	Australia
  Llanos	Venezuela
  Taiga	Europe and Asia

  Campos	Brazil

Tundra type of vegetation is characterized by mosses, lichens and very small shrubs.

Key Points

Mosses and Lichens:

• ​Mosses and Lichens are found in Tundra vegetation.
• Mosses and lichens are simple organisms that grow on trees and rocks.
• Lichens break down rocks into the soil and later mosses and other shrubs grow on them.
• Mosses and lichens both are simple organisms and are considered to be non-vascular plants, out of which only mosses are plants and not lichens.
• Lichens are formed by a symbiotic relationship between algae or cyanobacteria and a fungus.
• Mosses have leaves and stem but do not have roots because of which they cannot transport water and do not produce flowers.
• They absorb nutrients and water from their immediate environments.
• It is a flowerless plant mostly found in wet, damp, and shady locations.
• Mosses can monitor urban pollution and respond to pollution by changing its density and shape.
• It can be used as a bio-indicator to measure the impact of atmospheric change, which further helps scientists to calculate air pollution and atmospheric alterations.

Lichen is usually mistaken for mosses but lacks leaves and stems of the moss.

The correct answer is 200 cm

Key Points

• Tropical evergreen forests are found in areas that receive more than 200 cm of rainfall per year.
• These forests are characterized by their dense canopy of trees, which helps to keep the forest floor cool and moist.
• Tropical evergreen forests are home to a wide variety of plants and animals, including many species that are found nowhere else in the world.

Additional Information

The correct answer is South America.

Key Points

• The Pampas are vast temperate grasslands primarily located in Argentina, Uruguay, and parts of Brazil in South America.
• This region is characterized by fertile soil, making it one of the most productive agricultural zones globally.
• The Pampas are known for supporting the cattle ranching and farming industries, particularly the production of wheat and corn.
• These grasslands are a crucial biome in South America and are mainly covered with grasses such as fescue, ryegrass, and clover.
• They are also home to a variety of species, including the pampas fox, rhea (a large flightless bird), and armadillos, which are native to this region.

Additional Information

• Grasslands as a Biome:
  • Grasslands are ecosystems where grasses are the dominant plant type. They are classified into temperate and tropical grasslands.
  • Examples include the Pampas (South America), Prairies (North America), and Steppes (Eurasia).
  • Grasslands play a critical role in carbon sequestration and are vital for livestock grazing.
• Climate of the Pampas:
  • The Pampas experience a temperate climate with distinct seasons.
  • Rainfall is moderate and well-distributed throughout the year, making it ideal for farming.
• Economic Importance:
  • The Pampas are often referred to as the "breadbasket" of South America due to their extensive agricultural output.
  • The region is a leading exporter of beef, grains, and other agricultural products.
• Environmental Concerns:
  • Overgrazing and intensive farming have led to soil degradation and loss of biodiversity in parts of the Pampas.
  • Efforts are being made to promote sustainable agricultural practices to protect this vital ecosystem.

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.
