Question

Quizplus · Accepted Answer

Organic molecules are composed of carbon atoms bonded to other carbon atoms or to other non-metallic elements such as hydrogen, oxygen, nitrogen, sulfur, and phosphorus. These carbon atoms are ultimately derived from carbon dioxide through processes such as photosynthesis or chemosynthesis. Therefore, choices B and C are correct. Additionally, plants incorporate carbon into organic molecules through photosynthesis, which means that choice A is also correct. Hence, the best choice is E.
