Question

1.6. Sierra is asked to demonstrate how carbon travels from the atmosphere to living organisms, then

Answer 1

Answer:

B. Animals do not use carbon dioxide as an energy source; they use carbohydrates.

Explanation:

The most readily form of energy that an animal requires is carbohydrate molecules. Monosaccharide carbohydrates can be easily broken down and hence are the best sources of energy. Carbohydrates are broken down in the process of cellular respiration to generate ATP. ATP is the energy driving molecule which is required by every cell of an organisms body to carry out its normal metabolic functions. Hence, animals use carbohydrates as a source of energy, not carbon dioxide.
