Effects of Light Spectra on Algal Growth

In a research study, scientists aimed to evaluate the effect of various light spectra on the growth rate of a specific type of algae. The algae were subjected to three different light spectra: Red light, Blue light, and Green light. Over a four-week period, the growth rate was measured by calculating the increase in biomass (measured in grams) weekly for each light spectrum. Data collected showed the following weekly biomass increases:

Red Light: Week 1: 2g, Week 2: 3g, Week 3: 4g, Week 4: 5g

Blue Light: Week 1: 4g, Week 2: 6g, Week 3: 9g, Week 4: 10g

Green Light: Week 1: 1g, Week 2: 2g, Week 3: 2.5g, Week 4: 3g

Based on the data collected, which light spectrum resulted in the highest overall biomass increase over the four weeks?
