What is the natural rate of nitrogen fixation in earth’s ecosystems? what is the natural rate of nitrogen fixation in earth’s ecosystems? 2020 teragrams of nitrogen per year 100 teragrams of nitrogen per year 2020 kilograms of nitrogen per year 100 kilograms of nitrogen per year

100 teragrams of nitrogen per year

Explanation:

Nitrogen fixation in Earth's ecosystems is defined as a process where by nitrogen in air is transformed into ammonia or other related nitrogenous compounds. Generally, atmospheric nitrogen is referred to as molecular dinitrogen and it is a nonreactive compound that is metabolically useless to all but a few microorganisms. This process is vital to life due to the fact that inorganic nitrogen compounds are needed for the biosynthesis of amino acids, protein, and all other nitrogen-containing organic compounds. Thus, the natural rate of nitrogen fixation in Earth's ecosystems is 100 tetragrams of nitrogen per year.
