Describe a model that illustrates the role of photosynthesis and cellular respiration in the cycling of carbon among the biosphere, atmosphere, hydrosphere, and geosphere.

• Photosynthesis in plants absorbs carbon dioxide from the atmosphere, and cellular respiration in animals releases it back.

• Photosynthesis in plants releases carbon dioxide, and cellular respiration in animals absorbs it.

• Photosynthesis in plants absorbs oxygen, and cellular respiration in animals releases it.

• Photosynthesis in plants and cellular respiration in animals both absorb carbon dioxide.

Evaluate the impact of human activities on the carbon cycle and propose a solution to mitigate these effects.

• Human activities increase carbon emissions; a solution is to reduce fossil fuel use and increase reforestation.

• Human activities decrease carbon emissions; a solution is to increase fossil fuel use.

• Human activities have no impact on the carbon cycle; no solution is needed.

• Human activities increase carbon storage; a solution is to decrease reforestation.
