Which compares the gas is released by fertilizers and gases from landfills?
A. Chemicals from fertilizers can release methane while landfills release nitrous oxide
B. Chemicals from fertilizers can release methane while landfills release carbon dioxide
C. Chemicals from fertilizer can release carbon dioxide while landfills release methane
S. Chemicals from fertilizers can release nitrous oxide while landfills release methane
B. Chemicals from fertilizers can release methane while landfills release carbon dioxide
The correct answer is B. Chemicals from fertilizers can release methane while landfills release carbon dioxide.
To compare the gases released by fertilizers and gases from landfills, we need to understand the different gases that can be emitted from each source.
Fertilizers typically contain nitrogen-based compounds that can undergo chemical reactions and release gases. One of the main gases released by fertilizers is nitrous oxide (N2O), which is a potent greenhouse gas and contributes to ozone depletion.
Landfills, on the other hand, produce gases as a result of the decomposition of organic waste. The main gases generated from landfills are methane (CH4) and carbon dioxide (CO2). Methane is produced when organic matter breaks down anaerobically, while carbon dioxide is produced during both aerobic and anaerobic decomposition processes.
Now, let's analyze the given options:
A. Chemicals from fertilizers can release methane while landfills release nitrous oxide: This option is not correct. Fertilizers release nitrous oxide, not methane. Landfills, however, release methane.
B. Chemicals from fertilizers can release methane while landfills release carbon dioxide: This option is correct. Fertilizers can release nitrous oxide, not methane. Landfills, however, release methane and carbon dioxide.
C. Chemicals from fertilizer can release carbon dioxide while landfills release methane: This option is not correct. Fertilizers release nitrous oxide, not carbon dioxide. Landfills release methane and carbon dioxide.
S. Chemicals from fertilizers can release nitrous oxide while landfills release methane: This option is not correct. Fertilizers release nitrous oxide, not methane. Landfills, however, release methane.
Therefore, the correct answer is B. Chemicals from fertilizers can release methane while landfills release carbon dioxide.
