  1. What is meant by natural vegetation? How do temperature and rainfall affect its distribution? Explain with examples.

Answer – Natural vegetation refers to the plant community that grows in an area without any direct or deliberate interference by humans. It includes forests, grasses, and shrubs.

Temperature and rainfall play a vital role in determining the type and distribution of natural vegetation:

In regions with high rainfall and warm temperature, such as the Western Ghats and North-Eastern India, Tropical Evergreen Forests thrive.

Areas with moderate rainfall (100–200 cm), such as Central India and parts of Myanmar, support Tropical Deciduous Forests.

Cold and dry regions, such as the Himalayas and Northern Europe, support Coniferous or Temperate Softwood Forests, which are adapted to snowfall and shorter growing seasons.

  1. Highlight any five points of distinction between Tropical Deciduous Forests and Coniferous Forests.

Answer –

Tropical Deciduous Forests

Coniferous Forests (Temperate Softwood Forests)

Found in tropical regions with summer rainfall.

Found in cold regions and high altitudes.

Trees shed leaves in dry season.

Trees do not shed leaves; appear evergreen.

Trees have broad, medium-sized leaves.

Trees have needle-shaped leaves.

Common trees: teak, sal, bamboo.

Common trees: pine, fir, deodar.

Animals: tiger, lion, elephant.

Animals: snow leopard, deer, golden eagle.

 

  1. ‘Forests are essential for maintaining an ecological balance.’ Justify the statement with suitable arguments.

Answer – Forests play a vital role in maintaining ecological balance due to the following reasons:

They absorb carbon dioxide and release oxygen, supporting life.

Forests act as natural habitats for wildlife.

Tree roots bind the soil and prevent soil erosion and floods.

Forests help in maintaining the water cycle and cause rainfall.

They regulate temperature and keep the climate cool.

Thus, forests are the “lungs of the Earth” and critical for survival.

  1. Explain the importance of wildlife.

Answer – Wildlife is an essential component of natural ecosystems. Its importance includes:

Maintains ecological balance by regulating food chains.

Supports biodiversity, which is crucial for environmental stability.

Enhances natural beauty, supporting tourism and employment.

Acts as natural indicators for disaster prediction (e.g., behavioral changes before earthquakes).

Dead and decaying animals contribute to soil fertility through humus.

  1. How are human beings responsible for the depletion of vegetation and wildlife?

Answer – Humans are largely responsible for the decline in vegetation and wildlife due to:

Deforestation for agriculture, industries, and settlements.

Poaching and hunting of wild animals for commercial gains.

Urbanization leading to habitat destruction.

Pollution and climate change caused by human activities.

Overexploitation of forest resources and shifting cultivation.

These actions disrupt ecosystems and lead to the extinction of many species.

Value Based Question

Chipko Movement

The Chipko Movement was based on the Gandhian philosophy of non-violence and aimed at the protection and conservation of forests from destruction. This agitation inspired the women. They hugged the trees and said if the trees were to be cut, they would have to first kill the women embracing them.

Women were the worst affected by this deforestation as it was causing water shortage, Ian s , of firewood and fodder. They believed in traditional relationship of forest and humans. For them fight for survival.

  1. Why is the Chipko Movement called a fight for survival?

Answer – The Chipko Movement is called a fight for survival because it aimed at protecting forests, which were essential for the daily lives of the local communities—especially women. Forests provided them with water, firewood, fodder, and food, and their destruction threatened their livelihood, culture, and environment. The women who participated were fighting not just for trees, but for their basic needs and future existence.

  1. Mention any three lessons which all of us learn from this movement.

Answer – Conservation is everyone’s responsibility – Even common people, especially women, can play a powerful role in protecting nature.

Non-violent resistance is effective – Peaceful protest can bring about real change.

Forests are life-givers – We must understand and respect the deep connection between nature and human survival.
