उत्तर
- Plants produce biomass by the process of photosynthesis in which solar energy is used to prepare carbohydrates and oxygen.
- Biomass includes forest residues, crop residues, etc.
- For production of biofuel, biomass is harvested and transported for threshing. The residue left after threshing contains cellulose, which is later on converted to glucose.
- The glucose is then converted to liquid fuel through fermentation, which is used for different purposes.
- Biofuels are renewable sources of energy.
- They are available in solid (dung, crop residue), liquid (vegetable oils, alcohol) and gaseous (gobar gas) forms.
- Biofuels are easily available in sufficient amounts.
