Which compares the gases released by fertilizers and gases from landfills?(1 point)
Responses
A. Chemicals from fertilizers can release methane, while landfills release carbon dioxide.
B. Chemicals from fertilizers can release nitrous oxide, while landfills release methane.
C. Chemicals from fertilizers can release methane, while landfills release nitrous oxide.
.
D. Chemicals from fertilizers can release carbon dioxide, while landfills release methane.
B. Chemicals from fertilizers can release nitrous oxide, while landfills release methane.
To compare the gases released by fertilizers and landfills, we need to understand the types of gases that can be released from each source. Fertilizers typically contain chemicals that can release methane and nitrous oxide, while landfills primarily release methane and carbon dioxide.
Option A states that chemicals from fertilizers can release methane, while landfills release carbon dioxide. This statement is incorrect because fertilizers can also release nitrous oxide, not just methane.
Option B correctly compares the gases released by fertilizers and landfills. It states that chemicals from fertilizers can release nitrous oxide, while landfills release methane. Nitrous oxide (N2O) is a potent greenhouse gas that can be released from certain types of fertilizers, while methane (CH4) is commonly released from landfills.
Option C incorrectly states that chemicals from fertilizers release methane, while landfills release nitrous oxide. This statement is the opposite of what is true.
Option D incorrectly states that chemicals from fertilizers release carbon dioxide, while landfills release methane. While fertilizers can contribute to carbon dioxide emissions indirectly, it is mainly nitrous oxide that is released from fertilizers. Landfills, on the other hand, are known to release methane gas.
Therefore, the correct response is:
B. Chemicals from fertilizers can release nitrous oxide, while landfills release methane.
