B.plants take in Carbon dioxide and pass it on to animals.

Explanation:

Plants remove carbon dioxide from the atmosphere and use it during photosynthesis to create sugars. Animals that eat these plants digest these sugars to create energy. Animals then release carbon dioxide and other compounds that contain carbon via respiration and excretion. Once animals die, they release carbon compounds into the atmosphere and into the ground as they decompose.
