Question

Quizplus · Accepted Answer

Carbohydrates are the most plentiful biological molecules in the biosphere as they are the main source of energy for all living organisms. They are found in plants in the form of cellulose and starch, and in animals in the form of glycogen. Salts and minerals are necessary for biological processes, but they are not considered biological molecules. Proteins, fats, and nucleic acids are important molecules but are not as abundant in the biosphere as carbohydrates.
