Question

how does photosynthesis contribute to the carbon cycle? it removes carbon dioxide from the atmosphere. it creates nuclear radiation. it promotes the burning of fossil fuels. it sequesters carbon in fossil fuels.

Explanation:

Photosynthesis is a process where plants use sunlight, water, and carbon dioxide ($\ce{CO2}$) to produce glucose and oxygen. In the carbon cycle, this process specifically takes in $\ce{CO2}$ from the atmosphere (as plants absorb it for photosynthesis). The option "It creates nuclear radiation" is incorrect as photosynthesis has no relation to nuclear processes. "It promotes the burning of fossil fuels" is wrong because photosynthesis is a natural process in plants and not linked to human - induced fossil fuel burning. "It sequesters carbon in fossil fuels" is also incorrect as the sequestration in fossil fuels is a long - term geological process (like the burial and transformation of ancient plant and animal matter over millions of years), not directly part of the photosynthesis process in the carbon cycle.

Answer:

It removes carbon dioxide from the atmosphere.
