Living organisms can incorporate ________ into their metabolism.

Question

nitrates
nitrates - not selected, this is the correct answer

nitrites incorrect
why is that one correct and that one not

Answer 1

Living organisms can incorporate nitrates into their metabolism primarily through the process of nitrogen assimilation. Nitrates (NO3-) are a form of nitrogen that plants, for example, can absorb from the soil and then convert into amino acids and other organic molecules essential for their growth and development.

On the other hand, nitrites (NO2-) are generally a less stable and often intermediate form of nitrogen in the nitrogen cycle. While some organisms can utilize nitrites, they are not as commonly absorbed and utilized directly by most plants or organisms. Instead, nitrites are usually converted into nitrates before being incorporated into metabolic processes.

In summary, nitrates are the more common and readily usable form of nitrogen for many living organisms, making the incorporation of nitrates into metabolism the correct choice.

Answer 2

1 sentence

Answer 3

Living organisms can incorporate nitrates into their metabolism, as they are a primary source of nitrogen for growth, while nitrites are typically an intermediate form that is not commonly used directly.

Answer 4

shorter

Answer 5

Living organisms incorporate nitrates into their metabolism, while nitrites are usually an intermediate form not directly utilized.

Answer 6

Answer 7

Living things use nitrates for food and growth, but they usually don’t use nitrites because they’re just a middle step.
