Effect of Light Intensity on Photosynthesis

Medium Data Representation Interpreting Experimental Data

In an experiment designed to investigate the effect of light intensity on the rate of photosynthesis, a group of scientists measured the oxygen output of aquatic plants under different light levels. The data collected is summarized in the table below:

Light Intensity (μmol/m²/s) | Oxygen Output (mg O₂/L/hr)

0 | 0

50 | 2

100 | 5

150 | 7

200 | 8

250 | 8

Based on the data presented, what can be inferred about the relationship between light intensity and the rate of photosynthesis?

The rate of photosynthesis increases indefinitely with increasing light intensity.

Photosynthesis is maximized at light intensities above 200 μmol/m²/s.

A light intensity of approximately 150 μmol/m²/s provides maximum oxygen output.

There is no relationship between light intensity and the rate of photosynthesis.
