B) provides energy, which is converted to chemical energy.
C) directly causes ATP production.
D) provides heat energy, which is converted to chemical energy.
E) drives many enzymatic reactions.

Answer 1

Answer:

The correct answer is B)

Explanation:

Photosynthesis refers to the biological process through which plants and algae feed themselves. Plants can be considered akin to living solar panels: first, they absorb carbon dioxide through their leaves and water through their roots, and store them. Then, when exposed to light, they use this light energy to break down the carbon dioxide and water into carbohydrates, which is their main source of energy, and oxygen, which is exhaled out as a by product of this chemical reaction.
