Photosynthesis is the _____ reaction by which plants produce complex food molecules (sugars). This process requires an energy input from _____ to occur. In this reaction, the ______ carbon dioxide and water combine to form _______ such as glucose and oxygen gas. Photosynthesis is an important part of the carbon cycle because it removes _____ from the atmosphere. Through chemical reactions, it rearranges the atoms into other forms of useable carbon molecules for the plant and releases ______ back into the atmosphere.

Photosynthesis is the **chemical** reaction by which plants produce complex food molecules (sugars). This process requires an energy input from ** sunlight** to occur. In this reaction, the **reactants** carbon dioxide and water combine to form **products** such as glucose and oxygen gas. Photosynthesis is an important part of the carbon cycle because it removes **carbon dioxide** from the atmosphere. Through chemical reactions, it rearranges the atoms into other forms of usable carbon molecules for the plant and releases **oxygen** back into the atmosphere.
