Living organisms can incorporate ________ into their metabolism.(1 point)

Question

nitrogen gas

ammonia

Answer 1

Living organisms can incorporate ammonia into their metabolism. Ammonia is a form of nitrogen that can be directly used by organisms in processes such as the synthesis of amino acids and nucleotides. In contrast, nitrogen gas (N2) must first be converted into a usable form through processes like nitrogen fixation before it can be incorporated into metabolic pathways.
