Question 2.
Why do we need to conserve our natural vegetation?
Answer:
Our natural vegetation includes Tropical Evergreen Forests, Tropical Deciduous Forests, Thorny Forests, Mountain vegetation and Mangrove Forests. But today our forests are being cut speedily which has created several problems. Increase in soil erosion, floods, landslides and extension of desert area are some of them. All these disturb the ecological balance on the earth. The forests are the source of various products. They help in purifying the air. They reduce temperature and increase the amount of rainfall. Forests provide shelter to wildlife. It is, therefore, essential to conserve them.
Question 3.
Highlight two main features of the retreating monsoon.

Why does the natural vegetation in the Himalayan mountains change with altitude?
Answer:
It is because the temperature and rainfall decreases with height. At the foothills upto the height of 1000 metres, monsoon type of forests are found. As we go higher, the monsoon-type forests are replaced by trees having broad leaves. This type of forests is found upto the height of 2000 metres. The belt of coniferous trees start from the height of 1600 metres upto 3300 metres. The coniferous belt is succeeded by the alpine vegetation.
Question 5.
What efforts have been made in India to preserve our rich wildlife?

In order to preserve our rich wildlife, several wildlife sanctuaries and national parks have been set up all over India. A few scheme for the conservation and protection of our rich biological diversity has been undertaken. Under these schemes, many biosphere reserves have been set up in different parts of India. Project Tiger was launched in 1973 to protect tigers and Project Elephant was launched in 1991 by the Government of India to protect elephants.
