Our analysis is on the effect of algae, a phototrophic organism, on water quality and biodiversity. Algae growth thrives due to excess nutrients coming from agricultural runoff, notably from fertilizers containing nitrogen and phosphorus compounds, leading to eutrophication and competition (Gilbert & Burford, 2017). There’s a marked increase in certain species while other organisms decrease, reinforcing the loop between algae, eutrophication, decomposition, and increased greenhouse gasses (Amorim & Moura, 2021). Scientists have tried to find impacts of algae blooms on the environment but food chains are complex and the change in biodiversity is still in question. Our goal is to use the open data sources on algae growth, aquatic organisms (benthic macroinvertebrates), and water quality to analyze the correlation between algae growth and aquatic biodiversity.
