What disadvantage does biomass energy share with fossil fuel energy?

B. It leads to air pollution

To determine the disadvantage that biomass energy shares with fossil fuel energy, we can compare the two sources of energy.

Biomass energy refers to the use of organic material, such as plants and wood, to produce heat and electricity. Fossil fuel energy, on the other hand, comes from non-renewable sources like coal, oil, and natural gas. Both sources have their own set of disadvantages.

A. Limited supply: While biomass energy relies on renewable organic material, such as plants, it does have limitations. The availability and supply of biomass depend on factors such as agricultural practices, land availability, and climate conditions. Similarly, fossil fuels are finite resources that are being depleted at a rapid rate. Therefore, both biomass and fossil fuel energy face supply limitations, making option A incorrect.

B. Air pollution: Both biomass and fossil fuel energy can contribute to air pollution. Burning biomass, such as wood or agricultural residues, can release particulate matter and other pollutants into the air. Similarly, burning fossil fuels releases greenhouse gases and air pollutants such as sulfur dioxide, nitrogen oxides, and carbon monoxide. Hence, option B is correct.

C. Disruption of water ecosystems: Biomass energy does not directly disrupt water ecosystems. However, in some cases, the production of biomass may require water usage for irrigation or processing, which could affect water availability or quality. Fossil fuel energy, on the other hand, can lead to water pollution through spills and leaks during extraction, transport, and storage. Therefore, the disruption of water ecosystems is more associated with fossil fuel energy rather than biomass energy. Option C is incorrect.

D. Expensive to use: The cost of biomass energy production depends on various factors, including the type of feedstock, processing, and technology used. Similarly, fossil fuel energy costs include extraction, refining, and transportation expenses. Both sources can be expensive depending on the specific circumstances and infrastructure required. Consequently, option D is incorrect.

In conclusion, the disadvantage shared by both biomass energy and fossil fuel energy is that they both contribute to air pollution (option B).
