Question

10 which is an example of the cycling of carbon? a animals use the carbon in carbon dioxide for cellular respiration. b graphene is formed by causing carbon atoms to align in a particular way. c carbon dioxide is trapped in the atmosphere and contributes to the greenhouse effect. d a plant uses the carbon in carbon dioxide for photosynthesis and is eaten by an animal.

Explanation:

To determine the example of carbon cycling, we analyze each option:

• Option A: Animals release carbon dioxide during cellular respiration, but this is a part of the cycle, not a full - cycle example.
• Option B: Graphene formation is a synthetic process and not related to the natural carbon cycle.
• Option C: Carbon dioxide trapping in the atmosphere is about the greenhouse effect, not the cycling of carbon.
• Option D: A plant takes in carbon dioxide (from the atmosphere) during photosynthesis to make organic matter. Then, when the plant is eaten by an animal, the carbon is transferred to the animal. This shows the movement of carbon from the non - living (atmosphere) to the living (plant) and then to another living organism (animal), which is a part of the carbon cycle.

Answer:

D. A plant uses the carbon in carbon dioxide for photosynthesis and is eaten by an animal.
