Photosynthesis Rate and Light Wavelength

Very Hard Data Representation Understanding Graphs And Tables

A research study was conducted to examine the effects of different light wavelengths on the rate of photosynthesis in aquatic plants. The results are summarized in the table below:

Table 1: Rate of Photosynthesis vs. Light Wavelength

Wavelength (nm)	Rate of Photosynthesis (mg CO₂/m²/h)
400	20
500	40
600	60
700	30

Using the data provided, which statement accurately describes the relationship between the wavelength of light and the rate of photosynthesis?

Photosynthesis increases steadily with increasing wavelength.

Photosynthesis peaks at 600 nm and decreases at both lower and higher wavelengths.

There is no correlation between light wavelength and the rate of photosynthesis.

Photosynthesis only occurs at wavelengths below 600 nm.
