The carbon cycle circulates carbon dioxide and oxygen throughout an ecosystem. Which statement below best explains the role of photosynthesis and cellular respiration in the carbon cycle?

•  Animals take CO₂ out of the atmosphere through the process of photosynthesis and plants release CO₂ back into the atmosphere through the process of cellular respiration.
• Animals take O₂ out of the atmosphere through the process of cellular respiration and release O₂ back into the atmosphere through the process of cellular respiration.
• Plants take O₂ out of the atmosphere through the process of photosynthesis and animals release CO₂ into the atmosphere through the process of cellular respiration.
• Plants take CO₂ out of the atmosphere through the process of photosynthesis and animals release CO₂ back into the atmosphere through the process of cellular respiration.
