Question

level 2
photosynthesis is the process by which plants
a. turn co₂ into sugars
b. release co₂ to the atmosphere
c. turn sugars into co₂
d. all of the above

Explanation:

Photosynthesis is a process in plants where they use carbon dioxide ($\ce{CO_2}$), water, and light energy to produce glucose (a type of sugar) and oxygen. Option B describes releasing $\ce{CO_2}$ (which is respiration, not photosynthesis), and option C describes breaking down sugars (also respiration). So only option A is correct.

Answer:

A. Turn $\ce{CO_2}$ into sugars
