Question

Deep inside landfills, bacteria decompose organic wastes in a low oxygen environment. this anaerobic decomposition results in a mix of gases called landfill gas, which consists of about 50% ________.

Answer 1

During anaerobic decomposition, the composition of a the byproduct of this process called landfill gas is approximately 50 percent methane and 50 percent carbon dioxide with trace amounts (<1 percent) of nitrogen, oxygen, hydrogen sulfide, hydrogen, and nonmethane organic compounds

Step-by-step explanation:

Landfill gases are produced when bacteria break down organic waste.

Landfill gas is a mixture of hundreds of different gases. By volume, landfill gas typically contains 45% to 60% methane and 40% to 60% carbon dioxide. Landfill gas also includes small amounts of nitrogen, oxygen, ammonia, sulfides, hydrogen, carbon monoxide and other gases.

Answer 2

Methane

Step-by-step explanation:

Methane is a greenhouse gas considered more potent than carbon dioxide in creating a greenhouse effect. Landfills also produce carbon dioxide gas. Therefore, measures are usually taken on landfills to prevent global warming. Such measure includes; capturing and collection of the gas and the use of methanotrophs bacteria on the soil over the landfills to convert the produced methane into organic compounds.
