Photosynthesis Review

Which statement best explains the role of photosynthesis in the carbon cycle?

• Carbon dioxide is absorbed from the air, and carbohydrates are produced.

• Carbon dioxide is released into the air, and carbohydrates are broken down.

• Carbon and nitrogen are absorbed into the soil, and carbohydrates are produced.

• Carbon and nitrogen are released from the soil, and carbohydrates are broken down.
