Answer:
The bacteria convert free nitrogen into nitrogen-containing compounds, while the decomposers convert nitrogen-containing compounds into free nitrogen.
Explanation:
Nitrogen is an essential element for all living organisms. It is required for synthesis protein and nucleic acids and other nitrogenous compounds. Some nitrogen fixing organisms such as Rhizobium, fixes atmospheric nitrogen (N₂) into usable forms such as nitrate (NO₃⁻) or ammonium (NH₄⁺ ) in the soil. The plants take up (NO₃⁻) and (NH₄⁺ )by absorption from the soil by their roots and make protein and nucleic acids. Animals take up nitrogen by eating plants. On death of a plant or animal and the nitrogenous waste produced by animals, decomposers such as bacteria and fungi convert this organic nitrogen into ammonium (NH4⁺) and later into NO₂⁻ and NO₃⁻. Denitrifying bacteria change NO₃⁻ into free nitrogen (N₂).
The statement that compares the roles of nitrogen-fixing bacteria and decomposers in the nitrogen cycle is : ( C ) The bacteria convert free nitrogen into nitrogen-containing compounds while the decomposers convert nitrogen-containing compounds into free nitrogen
What Happens in the Nitrogen cycle
Nitrogen is essential for every living organism because in the Nitrogen cycle, nitrogen fixing organisms ( Rhizobium ) fixes nitrogen into the soil in the form of nitrate or ammonium ( NH₄⁺ ).
The nitrate and ammonium is taken up by the plants by absorption through its roots and is used for the production of protein and nucleic acids .as the plants die the bacteria convert the nitrogen compounds into free nitrogen.
Hence we can conclude that The bacteria convert free nitrogen into nitrogen-containing compounds while the decomposers convert nitrogen-containing compounds into free nitrogen
