Living organisms can incorporate **b. nitrates** and **d. ammonia** into their metabolism.
- **Nitrates** can be used by plants in the process of nitrogen assimilation to form amino acids and other important molecules.
- **Ammonia** can be directly incorporated into organic compounds through various metabolic pathways.
While **nitrites** can also be used, they are usually an intermediate in the nitrogen cycle. **Nitrogen gas** (N2) is generally not usable by most organisms directly and needs to be converted into a more reactive form through processes such as nitrogen fixation.
So, if you need to choose one answer from the options given, I would suggest **b. nitrates** or **d. ammonia** as the most appropriate.
