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).

Which of the following best describes physical science?
Alex17521 [72]

The study of matter and energy best describes physical science. Hence, option B is correct.

<h3>What is physical science?</h3>

Physical science is the study of the inorganic world.

Physics is a branch of science that studies matter and its motion through space and time, along with related concepts such as energy and force. Physics is one of the "fundamental sciences" because of the other natural sciences (like biology, geology etc.)

Thus the study of matter and energy best describes physical science. Hence, option B is correct.
