We've learned that plants use sunlight, water, and carbon dioxide to make their own food and release oxygen. How can 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.
