Question

which biogeochemical cycle is the most affected by human activities such as burning fossil fuels?
phosphorus cycle
carbon cycle
nitrogen cycle
water cycle

Explanation:

Burning fossil fuels releases large amounts of carbon dioxide into the atmosphere. This disrupts the natural carbon cycle, which involves the exchange of carbon between the atmosphere, oceans, land, and living organisms. The carbon cycle is thus significantly affected by this human activity.

Answer:

carbon cycle
