Question

Write the answers to the questions by observing the figure.

1. What type of fuel production process is shown in the figure?
2. Write two examples of each of the solid, liquid and gaseous fuels produced in this fuel production process?
3. How do microorganisms play their role in this process?

Answer 1

1. Biofuel is produced in the process shown in the figure.
2. Solid fuels: Dung, crop residue
   Liquid fuels: Vegetable oils, alcohol
   Gaseous fuels: Gobar gas, coal gas
3. For the production of biofuel, the residue left after the threshing of biomass contains cellulose, which is converted to glucose. This glucose is then converted to liquid fuel through microbial fermentation, which is used for different purposes.
