Quizplus · Accepted Answer

Carbon enters the biomass of animal bodies in the form of carbohydrates that are consumed as food. During the process of digestion, these carbohydrates are broken down into simpler forms such as glucose and then used by cells to produce energy and build body tissues. Carbon dioxide and carbon monoxide are gases that are not directly used by animals for their metabolism, while fossil fuels and calcium carbonate are not typically ingested by animals as food.
