Question

1. Explain the role of photosynthesis in the flow of energy between the plant and the person shown in the diagram.
2. Explain the role of photosynthesis in the cycling of matter between the plant and the person.

Answer 1

Photosynthesis has a role in the cycling of matter and flow of energy into and out of organisms. The flow of energy and cycling of matter can be traced. The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur.
