Question
Explain how photosynthesis contributes to the removal of carbon dioxide from the atmosphere.
Answer
Photosynthesis is the process by which plants and algae convert carbon dioxide and water into glucose and oxygen using sunlight. During this process, carbon dioxide is absorbed from the atmosphere, effectively reducing its concentration.
Explanation
A strong answer should directly address the approved learning objective to explain that photosynthesis removed carbon dioxide from the atmosphere. This question belongs to How oxygen increased within The composition and evolution of the Earth's atmosphere, so the response should use that exact curriculum context rather than a generic statement. The answer is correct when it names the key idea, explains the link to carbon dioxide, and keeps the wording specific to AQA GCSE revision.
Common mistake
Misunderstanding Photosynthesis
Students often think that photosynthesis only produces oxygen without recognizing that it also removes carbon dioxide from the atmosphere.
Emphasize that photosynthesis is a process where plants and algae convert carbon dioxide and water into glucose and oxygen, thus removing carbon dioxide from the atmosphere.
