Question

10 which two processes form a cycle, with the products of one process becoming the reactants of the other?
cellular respiration and photosynthesis
erosion and bioremediation
photosynthesis and erosion
bioremediation and cellular respiration

Explanation:

Cellular respiration uses glucose ($C_6H_{12}O_6$) and oxygen ($O_2$) (products of photosynthesis) to produce carbon dioxide ($CO_2$) and water ($H_2O$). Photosynthesis uses $CO_2$ and $H_2O$ (products of cellular respiration) to produce $C_6H_{12}O_6$ and $O_2$. Erosion is the movement of soil and rock; bioremediation is using organisms to clean pollutants. They don't form such a cycle with photosynthesis or cellular respiration.

Answer:

cellular respiration and photosynthesis
