Question 4. Name different types of vegetation found in India and describe the vegetation of high altitudes.
Answer: The different types of vegetation found in India are listed below:
-
Tropical evergreen forests
-
Tropical deciduous forests
-
Tropical thorn forests and scrubs
-
Montane forests
-
Mangrove forests
The vegetation of high altitudes are Montane Forests. In mountainous areas, the decrease in temperature with increasing altitude leads to the corresponding change in natural vegetation. As such, there is a succession of natural vegetation belts in the same order as we see from the tropical to the tundra region. The wet temperate type of forests are found between a height of 1000 and 2000 metres. Evergreen broad-leaf trees such as oaks and chestnuts predominate. Between 1500 and 3000 metres, temperate forests containing coniferous trees like pine, deodar, silver fir, spruce and cedar, are found. These forests cover mostly the southern slopes of the Himalayas and places having high altitude in southern and northeast India.
At higher elevations, temperate grasslands are common. At high altitudes, generally more than 3,600 meters above sea level, temperate forests and grasslands give way to the Alpine vegetation. Silver fir, junipers, pines and birches are the common trees of these forests. 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 like the Gujjars and the Bakarwals. At higher altitudes, mosses and lichens form part of tundra vegetation. The common animals found in these forests are Kashmir stag, spotted dear, wild sheep, jack rabbit, Tibetan antelope, yak, snow leopard, squirrels, Shaggy horn wild ibex, bear and rare red panda, sheep and goats with thick hair.
The characteristics of vegetation in high altitudes are as follows:
-
Alpine vegetation is found in altitudes above 3600 m.
-
Trees in these areas are junipers, birches and pines.

Question 5. Several species of plants and animals are endangered in India. Why?
Answer: The reasons are as follows:
-
Increasing population
-
Pollution
-
Deforestation
-
Hunting by poachers.
Question 6. Why has India a rich heritage of flora and fauna?
Answer:
-
India is a country with diverse relief features
-
Availability of different types of soil
-
Variation in climatic conditions
Question 7. Define an Ecosystem.
Answer: An ecosystem is a community of plants, animals and smaller organisms that live,feed, reproduce and interact in the same area or environment. Some ecosystems are very large. For example, many bird species nest in one place and feed in a completely different area. On the other hand, some ecosystems may be physically small, such as you would find in a meadow at the edge of a forest, or in a coral reef in the ocean.How does everything fit together in a forest ecosystem versus a meadow ecosystem?
While some species may be found naturally in both areas, the species that live in the forest ecosystem are usually very different from those that inhabit the meadow, even though the two environments are right next to each other. In other words, if we protect existing natural habitats, we will help to maintain biodiversity (biodiversity is the variety of life in all its forms, levels and combinations). Unfortunately, natural habitats and their ecosystems are more and more endangered because of the damaging environmental effects of growing human populations everywhere.

Natural Vegetation and Wildlife Class 9 Summary
Chapter 5 of the NCERT Class 9 Geography book is about "Natural Vegetation and Wildlife." This chapter explores the various types of plant life and animals found across the world, explaining how they adapt to their environments.
Types of Natural Vegetation:
-
Forests: These are dense areas with many trees. They can be divided into three main types:
-
Tropical Forests: Found in warm and humid regions, such as the Amazon Rainforest. These forests are rich in diverse plant and animal species.
-
Temperate Forests: Located in regions with four seasons, like parts of North America and Europe. These forests have a mix of broadleaf trees and some conifers.
-
Boreal Forests (Taiga): These forests are in cold regions with short summers, such as in Canada and Russia. They mostly have coniferous trees like pines and firs.
-
Grasslands: These areas are dominated by grasses with few trees. There are two main types:
-
Savannas: Found in tropical regions like Africa. These grasslands have scattered trees and experience a wet and dry season.
-
Temperate Grasslands: Located in regions with hot summers and cold winters, such as the prairies in North America. They have more grass and fewer trees.
-
Deserts: Deserts are very dry with very little rainfall. Vegetation is scarce, and plants like cacti are adapted to conserve water. Animals in deserts, such as camels and lizards, are also adapted to the harsh conditions.
-
Tundra: This type of vegetation is found in cold areas near the poles. The tundra has very low temperatures and short growing seasons. Plants here include mosses and lichens, and animals like polar bears and arctic foxes are adapted to extreme cold.
Wildlife: Each type of vegetation supports specific wildlife. Tropical forests have diverse animals, while tundras are home to animals adapted to cold climates. Understanding and protecting these ecosystems is crucial for maintaining ecological balance.
