Question

the following diagram describes the carbon cycle. which arrow best represents the process of photosynthesis? choose 1 answer: a arrow i b arrow ii c arrow iii d arrow iv

Explanation:

Photosynthesis is the process where producers (like plants) use sunlight, carbon dioxide ($\ce{CO_2}$), and water to make glucose and oxygen. In the carbon cycle diagram, producers take in $\ce{CO_2}$ from the atmosphere to perform photosynthesis. Arrow IV shows $\ce{CO_2}$ moving towards producers (trees), which matches the input of $\ce{CO_2}$ for photosynthesis. Arrows I, II, and III don't represent the intake of $\ce{CO_2}$ by producers for photosynthesis.

Answer:

D. Arrow IV
