Compare the biodiversity indices to one another. State a claim about the effect of pollution on the biodiversity of the stream ecosystem. Describe how the pollution levels affect the species richness and biodiversity of the stream. Justify your claim with evidence. Describe the difference in species richness you observed. Explain how human intervention can change biodiversity in positive ways.
