Light-independent reactions are the second stage of photosynthesis. They make sugars. Light-independent takes place in the stroma and doesn't require light. They need carbon dioxide (CO2) from the atmosphere to build the sugars. These sugars are used to build starches and cellulose in a cycle of chemical reactions.
There are more than simply 4 biological compounds in the human body. I suppose to categorise, the question is hinting towards the molecules like Carbohydrates ( Poly and mono saccharides ) Proteins ( Polypeptides Made of amino acids) and Fats. There is also water, but I'm hesitant to class that as a biological compound, as it's not organic.
