Q. According to the heterotroph hypothesis, the first life on the earth was able to

B) Feed upon carbohydrates produced by autotrophs

Explanation
After the aggregates became so large, some organisms developed the ability to ingest smaller organic molecules. This is heterotrophic nutrition. As the seas became filled, some developed the ability to change the light energy into usable energy called glucose. This is autotrophic nutrition and according to the heterotroph hypothesis, autotrophic nutrition came after heterotrophic nutrition
