b. Macroinvertebrates-invertebrates that you can see without magnification-are indicator species often surveyed when assessing aquatic ecosystems. The following data table and graph represent macroinvertebrates sampled in two different streams, Stream A and Stream B. Using the data, develop a claim about the overall and relative water quality of the streams and support your claim with at least two pieces of evidence for each stream.
