Multiple Choice Questions (MCQs)

Q1: Tropical evergreen forests are not found in which of the following regions?
(a) Amazon River Basin
(b) Congo River Basin
(c) Sahara Desert
(d) Southeast Asia
Ans: (c) Sahara Desert
Tropical evergreen forests are found in regions with heavy rainfall and high humidity, such as the Amazon and Congo river basins, and Southeast Asia. The Sahara Desert is a hot desert with very little rainfall, making it unsuitable for tropical evergreen forests.

Q2: Which of the following is a characteristic feature of tropical deciduous forests?
(a) Trees retain their leaves throughout the year.
(b) Trees shed their leaves in the dry season.
(c) Dense undergrowth of bushes and shrubs is absent.
(d) Thick canopy prevents sunlight penetration.
Ans: (b) Trees shed their leaves in the dry season
In tropical deciduous forests, trees shed their leaves during the dry season to conserve moisture. This adaptation allows them to survive seasonal changes in rainfall.

Q3: Which type of tree is not commonly found in temperate evergreen coniferous forests?
(a) Spruce
(b) Fir
(c) Oak
(d) Pine
Ans: (c) Oak
Temperate evergreen coniferous forests, also known as taiga, primarily consist of coniferous trees such as spruce, fir, and pine. Oak is typically found in deciduous forests.

Q4: Mediterranean forests are adapted to which type of climate?
(a) Hot and wet summers, cold and dry winters
(b) Hot and dry summers, cool and wet winters
(c) Constant rainfall throughout the year
(d) Bitterly cold winters and short warm summers
Ans: (b) Hot and dry summers, cool and wet winters
Mediterranean forests are adapted to a climate with hot and dry summers and cool and wet winters. This climate is typical of regions around the Mediterranean Sea.

Q5: Which of the following animals is not typically found in temperate deciduous forests?
(a) Wolf
(b) Brown bear
(c) Camel
(d) Lynx
Ans: (c) Camel
Camels are adapted to desert environments and are not typically found in temperate deciduous forests, where wolves, brown bears, and lynxes are common.

Q1: Tropical evergreen forests are also known as ___________ or selvas.
Ans: tropical rainforests
Tropical evergreen forests, with their dense vegetation and high biodiversity, are also known as tropical rainforests or selvas.

Q2: The main type of vegetation in deserts is ___________, which are drought-resistant.
Ans: xerophytic plants
Xerophytic plants, which are adapted to dry, hot conditions, are the main type of vegetation in deserts.

Q3: In tropical grasslands, the main vegetation type is ___________, which can grow more than 2 meters in height.
Ans: tall coarse grass
Tall coarse grass, often referred to as elephant grass, is the dominant vegetation in tropical grasslands.

Q4: Temperate grasslands are characterized by ___________, and the region experiences extremes of temperature.
Ans: short, soft grasses
Temperate grasslands feature short, soft grasses and experience extreme temperature variations between seasons.

Q5: ___________ forests are found in equatorial regions with heavy rainfall throughout the year.
Ans: Tropical evergreen
Tropical evergreen forests thrive in equatorial regions where heavy rainfall and high humidity are present throughout the year.

True/False

Q1: Deserts are typically found in regions with high annual rainfall.
Ans: False
Deserts are characterized by their extremely low annual rainfall, not high.

Q2: Mangrove forests grow in swampy and deltaic tracts.
Ans: True
Mangrove forests are adapted to grow in swampy and deltaic environments, often at the mouths of rivers.

Q3: The vegetation in polar deserts mainly consists of large trees.
Ans: False
Polar deserts have harsh conditions that prevent the growth of large trees; only a few hardy plants like moss and lichen can survive.

Q4: Animals in tropical grasslands migrate to forest margins during the dry season.
Ans: True
To survive the dry season, animals in tropical grasslands often migrate towards forest margins or congregate near waterholes.

Q5: All types of natural vegetation provide food and shelter for wildlife.
Ans: True
Natural vegetation, regardless of the ecosystem, plays a crucial role in providing food and shelter for wildlife, thereby affecting biodiversity.
