Choose the correct gas for each question below. Which greenhouse gas is produced by manure or decomposing waste in landfills? Which greenhouse gas is produced by bacteria in soil and water using nitrogen-rich fertilizer? Which gas is responsible for about one quarter of the greenhouse effect?

- CH4 is produced by manure or decomposing waste in landfills.

- N2O is produced by bacteria in soil using nitrogen-rich fertilizer.

- CO2 is responsible for about one quarter of the greenhouse effect.

Explanation:

Hello,

At first, we must know that CH4 is produced by manure or decomposing waste in landfills due to the organic material that is decomposed via bacteria and others organisms metabolism.

Now, N2O is produced by bacteria in soil using nitrogen-rich fertilizer since the high-demand in agricultural processes implies the high usage of fertilizers which are nitrogen-rich and usable to promote bacteria metabolism.

Finally, CO2 is responsible for about one quarter of the greenhouse effect since fossil fuels, coal-based generated electricity and many other processes to produce or use energy imply the consumption of fuels which releases carbon dioxide by means of their combustion that produces the required energy.

Best regards.
