Natural Vegetation and Wildlife NCERT Intext Questions and Answers
Why are the southern slopes in Himalayan region covered with thick vegetation cover as compared to northern slopes of the same hills?
The northern slopes of the hills in the Himalayan region are at high altitude and have very low temperature or are snow covered. This does not allow much vegetation. On the other hand, in the southern slopes of the hills there are plains and valleys endowed with rivers, fertile soil and pleasant temperature. As a result, these regions have dense growth of vegetation.
Why have the western slopes of the Western Ghats covered with thick forests and not the eastern slopes?
The western slopes of the Western Ghats receive much more rain than the eastern slopes and the Western Ghats are considerably wetter than the dry Deccan to the east.

Name different types of Vegetation found in India and describe the vegetation of high altitudes.
Different types of vegetation found in India are:
- Tropical Evergreen Forests
- Tropical Deciduous Forests
- Tropical Thorn Forests and Scrubs
- Montane Forests
- Mangrove Forests Vegetation of high altitudes
At high altitudes, generally more than 3,600 metres above sea-level, temperate forests and grasslands give way to the Alpine vegetation. Common trees found in these forests are silver fir, junipers, pines and birches. However, they get progressively stunted as they approach the snow-line. Ultimately through shrubs and scrubs, they merge into the Alpine grasslands. These are used extensively for grazing by nomadic tribes. At higher altitudes, mosses and lichens form part of tundra vegetation.
Quite a few species of plants and animals are endangered in India. Why?
Few species of plants and animals are endangered in India because of the following reasons:
- Increase in population
- Large scale deforestation to bring land under cultivation and habitation
- Hunting by greedy hunters for commercial purposes
- Pollution due to chemical and industrial waste, acid deposits
- Urbanisation and industrialisation.
Why has India a rich heritage of flora and fauna?
(i) India is a diverse country with different relief features, for example, mountains, plateaus, plains, etc. Different types of vegetation are found in these regions and the vegetation give shelter to variety of wild life.
(ii) Different types of soils provide basis for different types of vegetation. The sandy soils of the desert support cactus and thorny bushes while wet, marshy, deltaic soils support mangroves and deltaic vegetation. The hill slopes with some depth of soil have conical trees.
(iii) The climate of India differs from north to south and east to west. Such climate supports a great variety of flora and fauna.
(iv) The variation in duration of sunlight at different places due to differences in latitude and altitude is also contributes to India’s flora and fauna. Due to longer sunlight, trees grow faster in summer.
(v) In India almost the entire rainfall is brought in by the advancing southwest monsoon and retreating northeast monsoons. Areas of heavy rainfall have more dense vegetation as compared to other areas of less rainfall. Needless to say that dense vegetation supports a great variety of animals.
