D Correct answer
Explanation

Many of the previous tsunamis were tamed by the coral reefs before hitting the coast, where they were absorbed by a dense layer of red mangrove trees. These flexible trees, with long branches growing right down into the sand below the surface of the sea, absorb the shock of tsunamis. Behind the red mangrove trees, there is a second layer of black mangrove trees, which are taller and slow down the waves.

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Forests maintain ecological balance. Forests help in maintaining the ecological balance in the following ways:

They absorb carbon dioxide and release oxygen. They provide the soil with the necessary humus content. They prevent soil erosion by binding the soil with tree roots. They check floods by holding rain water in subsoil. They increase moisture content of the air through transpiration. They provide natural habitat for wildlife.

  2. To take help of local people in conserving forest

  3. Both A and B

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Forests and wildlife are the natural resources which maintain ecological balance and biodiversity in the ecosystem. The forest provides shelter and food to the different species and thus need to be conserved because if the forests are not conserved, then it may affect these habitats with the extinction of species. Without proper management of forest and wildlife, the quality of soil, the water sources, and even the amount of rainfall may be affected. Without forest and wildlife, life would become impossible for human beings.

Some approaches towards the conservation of forests are:
→ Conversion of forests into national parks, sanctuaries. 
→ To take help of local people in the conserving forest. 
→ Not to allow the destruction of forests for making roads, dams and hotels etc. 
→ Planting of trees should be increased.
