Concept explainers
(a)
Interpretation:
The macronutrient which is the source of ethanol has to be given.
Concept introduction:
Biofuel:
The fuels like ethanol and biodiesel are examples for biofuels. They are produced from biomass materials.
Biofuels decreases the use of fossil fuels which emits green-house gases and also greater benefits will be there if cleaner feedstocks are used.
