Answer:-
(i) Difference Between Flora and Fauna
π± Flora | π Fauna |
---|---|
Refers to plants found in a specific region. | Refers to animals living in a specific region. |
Includes trees, shrubs, grasses, flowers, etc. | Includes mammals, birds, reptiles, insects, etc. |
Example: Teak, Bamboo, Mangroves in India. | Example: Tiger, Elephant, Peacock in India. |
(ii) Difference Between Tropical Evergreen and Deciduous Forests
π³ Tropical Evergreen Forests | π Deciduous Forests |
---|---|
Found in hot and humid regions with high rainfall (above 200 cm). | Found in areas with moderate rainfall (100β200 cm). |
Trees do not shed leaves seasonally, remain green all year. | Trees shed leaves in dry seasons to conserve water. |
Example: Rubber, Mahogany, Ebony trees. | Example: Sal, Teak, Neem trees. |
π Conclusion:
Flora and fauna represent plant and animal life in a region, while tropical evergreen and deciduous forests differ in rainfall, leaf-shedding, and vegetation type. πβ¨
Q. 4. Name different types of Vegetation found in India and describe the vegetation of
high altitudes.
Answer:-
β¨ Types of Vegetation in India & High Altitude Vegetation πΏπ
π³ Types of Vegetation in India:
India has a diverse range of vegetation due to its varied climate and geography. The main types are:
1οΈβ£ Tropical Evergreen Forests π²
- Found in regions with heavy rainfall (above 200 cm).
- Trees do not shed leaves and remain green throughout the year.
- Example: Rubber, Mahogany, Ebony (Western Ghats, Northeast India).
2οΈβ£ Tropical Deciduous Forests π
- Found in moderate rainfall areas (100β200 cm).
- Trees shed leaves in dry seasons to conserve water.
- Example: Sal, Teak, Neem (Central India, foothills of Himalayas).
3οΈβ£ Thorn & Desert Vegetation π΅
- Found in arid and semi-arid regions with very low rainfall.
- Plants have deep roots, thick stems, and spines to conserve water.
- Example: Cactus, Khejri, Acacia (Rajasthan, Gujarat).
4οΈβ£ Mangrove Forests π
- Found in coastal and tidal areas, where land meets the sea.
- Trees have stilt-like roots to survive in saline water.
- Example: Sundari Tree (Sundarbans, Andaman & Nicobar Islands).
5οΈβ£ Mountain & Alpine Vegetation ποΈ
- Found in high-altitude regions where temperatures are low.
- Trees are coniferous, adapted to withstand snow and cold.
- Example: Pine, Fir, Cedar (Himalayas, Nilgiris).
π² Vegetation of High Altitudes (Mountain & Alpine Forests):
πΉ Found in the Himalayas & other mountain regions above 3,000 meters.
πΉ Includes coniferous trees like Pine, Spruce, Fir, and Cedar which have needle-like leaves to retain moisture.
πΉ At higher altitudes, forests give way to Alpine Grasslands with short shrubs and hardy plants.
πΉ Above 4,500 meters, vegetation is almost absent due to extreme cold, and only mosses & lichens survive.
π Fun Fact: The Himalayan region has unique medicinal plants like Rhodiola (used for altitude sickness) and Dhoop (used in traditional healing)! πΏβ¨
Q. 5. Quite a few species of plants and animals are endangered in India. Why?
Answer:-
β¨ Reasons for Endangered Species in India πΏπ
India is home to rich biodiversity, but several species of plants and animals are endangered due to various threats.
πΉ Major Causes of Endangerment:
1οΈβ£ Deforestation & Habitat Loss π²π
- Large-scale cutting of forests for agriculture, urbanization, and industries reduces natural habitats.
- Animals like the Asiatic Lion & One-Horned Rhinoceros have limited territories due to habitat destruction.
2οΈβ£ Poaching & Illegal Trade πΉπ°
- Species like Tigers, Elephants, and Pangolins are hunted for their skin, ivory, and medicinal value.
- Illegal wildlife trade threatens rare species like Red Panda & Snow Leopard.
3οΈβ£ Climate Change & Pollution π¦οΈπ’οΈ
- Rising temperatures affect ecosystems, making survival difficult for marine life, Himalayan species, and coastal biodiversity.
- Water pollution impacts Gangetic Dolphins & aquatic plants in rivers.
4οΈβ£ Human-Wildlife Conflict π§π
- Expanding cities and agriculture push wildlife into human settlements, leading to conflicts & killings.
- Elephants and leopards often enter villages, causing destruction and risking their survival.
5οΈβ£ Invasive Species & Disease Spread π¦ π±
- Introduction of non-native species affects local flora and fauna.
- Diseases threaten fragile species like Amphibians & Coral Reefs.
π Examples of Endangered Species in India:
βοΈ Fauna: Bengal Tiger, Snow Leopard, Indian Pangolin, Gangetic Dolphin π
π
βοΈ Flora: Red Sandalwood, Blue Vanda Orchid, Medicinal Plants πΊπΏ
π‘ Solution:
To protect biodiversity, afforestation, wildlife conservation programs, legal protections, and sustainable development are essential! πβ¨
Q. 6. Why has India a rich heritage of flora and fauna?
Answer:-
β¨ Indiaβs Rich Heritage of Flora & Fauna πΏπ
India is one of the most biodiverse countries in the world, with a vast range of plants, animals, and ecosystems. This rich heritage is due to several factors:
πΉ Reasons for Indiaβs Biodiversity:
1οΈβ£ Diverse Climate & Geography π
- India has snow-covered Himalayas, deserts, rainforests, grasslands, and coastal areas, creating different habitats for wildlife.
- Varying temperatures and rainfall patterns support unique species in each region.
2οΈβ£ Varied Vegetation Zones π³
- India has Tropical Evergreen, Deciduous, Desert, Mangrove, and Alpine forests, each with distinct plant and animal life.
- Example: Mangroves in Sundarbans, Evergreen forests in Western Ghats, and Alpine vegetation in the Himalayas.
3οΈβ£ Monsoon Winds & Water Bodies π¦οΈ
- The Southwest Monsoon supports lush vegetation and diverse river systems like the Ganga, Brahmaputra, and Godavari, sustaining aquatic life.
- Lakes, wetlands, and rivers provide homes for crocodiles, Gangetic dolphins, and water birds.
4οΈβ£ High Endemism (Unique Native Species) πΎ
- India is home to many species found nowhere else, such as the Lion-tailed Macaque (Western Ghats) and Nilgiri Tahr.
- The Himalayas and Andaman & Nicobar Islands have many rare endemic plants and animals.
5οΈβ£ Sacred & Cultural Protection ππΏ
- Many plants and animals are worshipped or considered sacred, leading to conservation efforts.
- Example: Peepal tree, Banyan tree, Cow, Elephants have religious importance.
6οΈβ£ Government Conservation Efforts π
- India has 104 national parks, 566 wildlife sanctuaries, and 18 biosphere reserves to protect flora and fauna.
- Projects like Project Tiger, Project Elephant, and Wetland Conservation Programs ensure wildlife protection.
π Conclusion: Indiaβs rich heritage of flora and fauna is a result of natural diversity, climate variations, cultural values, and conservation efforts. It is our responsibility to protect and preserve this biodiversity! πΏβ¨
