Which Waste Products from an Organism Would Be Most Rich

Question

Which waste products from an organism would be most rich in carbon?
A) A deer
B) A mountain lion
C) A killer whale
D) None of the above

Accepted Answer

Deer are herbivores and their waste products, such as feces and urine, contain a lot of plant material that they have digested. Plants are rich in carbon as they use carbon dioxide during photosynthesis to make their own food. Therefore, the waste products of a deer would be most rich in carbon compared to carnivores like mountain lions or killer whales.
