Question

Microorganisms assimilate large amounts of all of the following except ______ into organic molecules.

1) nitrogen
2) phosphorus
3) sodium
4) sulfur

Answer 1

Microorganisms assimilate large amounts of nitrogen, phosphorus, and sulfur into organic molecules, but not sodium.

Step-by-step explanation:

Microorganisms assimilate large amounts of all of the macronutrients, including nitrogen, phosphorus, and sulfur, but they do not assimilate sodium into organic molecules. Nitrogen is an essential component of proteins and nucleic acids, and it can be fixed by certain bacteria. Phosphorus is necessary for the synthesis of nucleotides and phospholipids, while sulfur is part of the structure of some amino acids and vitamins.
