How can the class explain how animals complete the oxygen-carbon cycle? Animals take in the oxygen, but do not release gas as they use energy. Animals take in carbon dioxide and use it to make food. Animals take in oxygen and release nitrogen as waste. Animals take in oxygen and as they use energy, carbon dioxide is released as waste. Correct Answer Animals take in oxygen and as they use energy, carbon dioxide is released as waste. 8) Fill in the blanks using the available answer choices.
