Which of the following is produced by anaerobic decomposition in landfills?
A
Methane (CH_4)
B
Ozone (O_3)
C
Carbon monoxide (CO)
D
Nitrogen dioxide (NO_2)
Verified step by step guidance1
Understand the process of anaerobic decomposition, which occurs in environments lacking oxygen, such as landfills.
Recognize that during anaerobic decomposition, microorganisms break down organic matter and produce gases as byproducts.
Identify the common gases produced by anaerobic decomposition, focusing on methane (CH\_4) and carbon dioxide (CO\_2) as primary products.
Compare the given options: methane (CH\_4), ozone (O\_3), carbon monoxide (CO), and nitrogen dioxide (NO\_2), and determine which is typically produced in anaerobic conditions.
Conclude that methane (CH\_4) is the gas produced by anaerobic decomposition in landfills, as it is a major component of landfill gas generated by microbial activity in the absence of oxygen.
