3) Lakes in w atersheds dominated by calcareous glacial till have high concentrations of dissolved rbonate (Ca(НСО,h). Photosynthetic removal of CO, by aquatic plants and algae n result in the precipitation of insoluble calcite (CaCou) that may also co-precipitate phosphoru s -typically the limiting nutrient in aquatic systems. Charles Miller (Allegheny '15) collected leaves from 4 species of aquatic plants in Lake Pleasant, Erie County, PA, dissolved the precipitated calcite, and measured the amount of calcium deposited per gram of leaf mass on several dates during the growing season. His data are shown below. Are there any differences in calcite (measured as mg Ca/g leaf) deposition across species or time or any interaction between these two main effects?
