- D. Decomposition
Answer
The correct option is Photosynthesis. This answer is correct because it matches the approved learning objective to explain that photosynthesis removed carbon dioxide from the atmosphere in the subtopic How oxygen increased.
Explanation
The correct option is Photosynthesis. Photosynthesis is correct because it directly supports the approved learning objective to explain that photosynthesis removed carbon dioxide from the atmosphere. This belongs to the subtopic How oxygen increased within The composition and evolution of the Earth's atmosphere, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from How oxygen increased.
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.
