Question 1:

What is biomass?

Explanation: Biomass refers to plant and animal matter, including crops, agricultural residues, wood, and organic waste materials. It is used as a renewable source of energy.

Question 2:

Which of the following is a type of biofuel?

Explanation: Ethanol is a type of biofuel. It is produced by fermenting biomass, such as corn, sugarcane, or cellulosic materials, and is commonly used as a fuel additive or alternative to gasoline.

Question 3:

What is the main advantage of biomass energy?

Explanation: The main advantage of biomass energy is that it has low carbon emissions, as the carbon dioxide released during combustion is offset by the carbon dioxide absorbed by plants during photosynthesis. Additionally, biomass is a renewable resource and widely available.

Question 4:

Which of the following is not a form of biomass energy conversion?

Explanation: Photovoltaic conversion is not a form of biomass energy conversion. Photovoltaic systems convert sunlight directly into electricity using solar panels, whereas biomass energy conversion involves the combustion, fermentation, or gasification of biomass materials.

Question 5:

What is the primary use of biofuels?

Explanation: The primary use of biofuels is as a transportation fuel. Biofuels, such as ethanol and biodiesel, can be used as substitutes for gasoline and diesel in vehicles, reducing reliance on fossil fuels and decreasing carbon emissions.
