Here's why:
* Carbohydrates are the primary energy source for most organisms. They make up a large portion of plant structures (cellulose) and are found in many animal tissues.
* Proteins are crucial for structure and function, but they are generally less abundant than carbohydrates.
* Lipids (fats) are important for energy storage and insulation, but they are also less abundant than carbohydrates in most organisms.
* Nucleic Acids (DNA and RNA) are essential for genetic information, but they are present in much smaller amounts compared to carbohydrates.
While the specific proportions of these molecules can vary depending on the organism and tissue, carbohydrates are generally the most abundant organic molecules in living things.
