Question

Name the Macronutrient nonmetal which is important for protein
synthesis.Explain how it is cycled in atmosphere?

Answer 1

The main components of the organic compounds in a prokaryotic cell are macronutrients (such as carbon, hydrogen, oxygen, nitrogen, phosphorus, and sulfur) that make up important biomolecules, including proteins and nucleic acids.
Nutrients that are needed by prokaryotes in small quantities to perform cellular functions, including certain electron transport chain reactions, are known as micronutrients (e.g., iron, boron, chromium, and manganese).
Autotrophic prokaryotes are able to fix inorganic compounds, such as carbon dioxide, to obtain carbon, while heterotrophic prokaryotes use organic compounds as their source of carbon.

Answer 2

 Nitrate present in the soil is reduced to nitrogen by the process of denitrification by the bacteria present in the soil.
