Answer 1

Biogas can be a good substitute for

(a) fuelwood

• Biogas is a gas that is formed due to the breakdown of organic matter that too in the absence of oxygen.

• It can be produced from various raw materials. Some of the raw materials are sewage waste, plant waste, food waste, etc.

• Also in some places, it can be used as a good substitute for fuelwood as it would help to control deforestation. This would, in turn, lead to the improvement of our surroundings and ecosystem.

Answer 2

Bio-gas can be a good substitute for  fuel wood.

Option (A) is correct.

Explanation:

Bio-gas can be a good substitute for  fuel wood.

• The reason is that forests make up to 90 % of the environment clean.

• The forests are cutting and used as a source for energy consumption which is causing a great loss of trees along with the climate changes.

• Deforestation is also causing the soil erosion, as the upper layer of the soil is being washed away with water due to the deforestation.

• Therefore bio-gas should be replaced with fuel wood as it would have positive impact on the environment.
