Rate of Photosynthesis Experiments: Analyzing the Relationship between Light Intensity and Photosynthesis

The video tutorial explains an experiment conducted to study the relationship between light intensity and the rate of photosynthesis in pondweed. The experiment setup involves placing pondweed in a boiling tube with a hydrogen carbonate solution and varying the distance of a light bulb to measure the number of bubbles produced. The results are recorded in a tally chart and graphed to show a non-linear trend. The analysis concludes that as light intensity decreases, the rate of photosynthesis also decreases, supporting the hypothesis.

What trend did Matt observe in the number of bubbles produced as the distance from the light source increased?

Explain the relationship between light intensity and the rate of photosynthesis based on Matt's findings.
