Final answer:
The correct summary of a process during photosynthesis is the conversion of carbon dioxide and water into glucose and oxygen.
Step-by-step explanation:
The statement that summarizes a change that occurs during photosynthesis is: "Conversion of water and carbon dioxide into glucose and oxygen". Photosynthesis is a biological process where plants use sunlight to convert carbon dioxide and water into glucose (a sugar molecule) and oxygen. The energy from sunlight is captured and chemical reactions transform CO₂ and H₂O into CH₂O (a building block of sugar) and release O₂ into the air – a byproduct that is essential for animal life.
