Question 4. Give reasons:

The animals in the polar region have thick fur and thick skin.
Tropical deciduous trees shed their leaves in the dry season.
The type and thickness of vegetation changes from place to place.
?‍♂️Answer:

The animals in the polar region have thick fur and thick skin because of the following reasons:
Polar regions are very cold. .
Animals that do not have thick fur and thick skin cannot survive in these harsh and cold climates.;
They have to protect themselves from cold by thick fur and thick skin.

Tropical deciduous trees shed their leaves in the dry season because of the following reasons:
During the dry season, rainfall is scarce and water supply to plants and trees through their roots is reduced.
Transpiration occurs through leaves.
To reduce transpiration in dry season, trees shed their leaves.
The short supply of moisture through their roots keeps them alive during the dry season.

The type and thickness of vegetation changes from place to place because of the following reasons:
Climate (temperature and moisture)
Height from mean sea level – Slope
The thickness of the soil.
As these conditions vary from place to place, natural vegetation (types and thickness) also varies from place to place.

Vegetation and Wildlife SAQ

Question 1. Mention the major features of tropical evergreen forests.
?‍♂️Answer: Major features of tropical evergreen forests are:These forests are so dense that thick canopies are developed which do not allow the sunlight to penetrate inside the forest.
As there is no particular dry season, the trees do not shed their leaves altogether. This keeps the forest evergreen.
Hardwood trees such as rosewood, ebony and mahogany are found here.
Question 2. Mention the features of Mediterranean trees.
?‍♂️Answer: These trees adapt themselves to dry summers with the help of their thick barks and wax-coated leaves which help them reduce transportation.
Question 3. Write a short note tropical grasslands. 
?‍♂️Answer: Tropical grasslands occur on either side of the equator and extend till the tropics. This vegetation grows in the areas of moderate to low amount of rainfall. The grass can grow very tall, about 3 to 4 metres in height. Savannah grasslands of Africa are of this type. Common animals found here are elephants, zebras, giraffes, deer and leopards.
Question 4. Give cm account of the natural vegetation and wildlife found in the polar regions.
?‍♂️Answer: Polar regions are extremely cold. Therefore the growth of natural vegetation is very limited here. Only mosses, lichens and veiy small shrubs are found here. They grow during the very short summer. This is called Tundra type of vegetation. This vegetation is found in the polar areas of Europe, Asia and North America. The animals found here have thick fur and thick skin which protect them from the cold climatic conditions. Seal, walruses, musk-oxen, Arctic owl, Polar bear and snow foxes are some of the animals found in these regions.

Vegetation and Wildlife Long Answer Questions

Question 1. Discuss various types of forests. 
?‍♂️Answer: Types of forests: ,• Tropical evergreen forests
• Tropical deciduous forests
• Temperate evergreen forests
• Temperate deciduous forests
• Mediterranean vegetation
• Coniferous forests
1. Tropical evergreen forests. These forest are very dense and found in the regions near the equator and close to the tropics. These regions receive heavy rain throughout the year. The trees of these forests do not shed their leaves altogether and therefore they remain green all the time. Hardwood trees like rosewood, ebony and mahogany are found here.2. Tropical deciduous forests. These forest are found in the regions which experience seasonal changes. Trees shed their leaves in the dry season to conserve water. The hardwood trees like sal, teak, neem and shisham are found here. Animals like tigers, lions, elephants, langoors and monkeys are common in these forests.3. Temperate evergreen forests. These forests are commonly found along the eastern margin of the continents. They comprise both hard and softwood trees. For example, oak, pine, eucalyptus etc.4. Temperate deciduous forests. Trees of these forests shed their leaves in dry ‘season’. Oak, ash, beech, etc. are common trees here. Deer, foxes, wolves, etc. are common animals in these forests.5. Mediterranean vegetation. It is mostly found in the areas around the Mediterranean sea in Europe, Africa and Asia. Citrus fruits like oranges, figs, olives and grapes are commonly cultivated in the Mediterranean regions.6. Coniferous forests. They are also called Taiga. They are tall, softwood evergreen trees. Chir, pine, cedar is an important variety of trees in these forests. Silver, fox, mink, polar bear are the common animals found here.
Question 2. Describe different types of grasslands. 
?‍♂️Answer: Different types of grasslands are:• Tropical grasslands
• Temperate grasslands
• Thorny bushes
• Tropical grasslands. This type of vegetation grows in the areas of moderate to low amounts of rainfall. • • The grass here can grow very tall, about 3 to 4 metres in height. Savannah grasslands of Africa are of this type. Common animals found here are elephants, zebras, giraffes, deer, leopards etc.
Temperate grasslands. This type of vegetation is found in the mid-latitudinal zones and in the interior part of the continents. Grass here is usually short and nutritious. Common animals found in this region are wild buffaloes, bison, antelopes etc.
Thorny bushes. These are found in the dry desert-like regions. Tropical deserts are located on the western margins of the continents, which are characterised by scarce vegetation.
