Question

which statement best describes the relationship between photosynthesis and cellular respiration?
photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.
photosynthesis is part of the carbon cycle, and cellular respiration is not.
only plants perform photosynthesis, and only animals perform cellular respiration.
photosynthesis releases carbon into the atmosphere, and cellular respiration removes carbon from the atmosphere.

Explanation:

Photosynthesis uses carbon dioxide (removes carbon from the atmosphere) and produces oxygen. Cellular respiration uses oxygen and produces carbon dioxide (releases carbon back into the atmosphere). Both processes are part of the carbon cycle. Plants and animals (and many other organisms) perform cellular respiration.

Answer:

Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.
