Explanation:
Carbon fixation is also referred to as carbon assimilation is simply defined as the conversion by living organisms of inorganic carbon to the organic ones.

The correct answers are "sugar" and "amino acids." We can find this answer within the name itself. The prefix "glyco-" relates to producing sugar (think glucose and glycogen, which are both forms of sugar), and the suffix "proteins" is exactly that: proteins (which are made up of amino acids). So, when we say glycoprotein, we can think "sugar-protein," which gives us our answer.
They start as single cell orginisms then they evolve from there.
