Photosynthesis and Respiration Concepts

The video tutorial discusses question 14 from the 2023 Integrated Science paper, focusing on the carbon cycle. It explains the processes of photosynthesis and respiration, identifying where these occur in a given diagram. Photosynthesis is described as the absorption of carbon dioxide by plants, while respiration is the release of carbon dioxide by plants or animals. The tutorial helps students understand these processes and identify them in the context of the carbon cycle.
