Answer: It helps cells make proteins.
It provides a form of usable nitrogen.
Explanation:
Nitrogen cycle is one of the biogeochemical cycles. It involves the distribution of nitrogen in various spheres of earth.
Nitrogen is essential element for growth and abundance of plants. Nitrogen present in the atmosphere cannot be used by the plants directly for growth. Instead the bacteria present in soil convert the atmospheric bacteria into plant useable forms such as ammonia, nitrates and nitrites.
It helps cells make proteins.The ammonia is used for synthesis of aminoacids which are further required for synthesis of proteins.
The statements 'it helps cells make proteins' and 'it provides a form of usable nitrogen' BEST describe the importance of the nitrogen cycle to living things.
- Nitrogen is a fundamental element in all organisms because it is a component of different types of biomolecules such as proteins and nucleic acids.
- In nucleic acids (either DNA or RNA), nitrogen is a fundamental constituent of nitrogenous bases (i.e., Adenine, Guanine, Cytosine, and Thymine).
- The nitrogen cycle refers to the process by which this element circulates in the air, soil and living things.
- For example, around 78% of the volume of the atmosphere (air) is composed of nitrogen gas.
In conclusion, the statements 'it helps cells make proteins' and 'it provides a form of usable nitrogen' BEST describe the importance of the nitrogen cycle to living things.
