Examine the four following scenarios Situation A Situation B Situation C Situation D A small suburban pond collects runoff from lawns treated with fertilizers. Algae appear in patches, and some plant stems float near the surface, while aquatic insects are less abundant along the edges. Occasional rain events increase the amount of nutrient-rich water entering the pond. A pond near a road accident site has a thin layer of oil floating on the surface. Aquatic insects and small fish appear stressed or absent, and plant leaves are coated with a slick residue. The water has an oily sheen, but algae remain sparse. A pond receives water from nearby orchards treated with chemical pesticides. Some amphibians and insects are found dead along the shore, and water shows no excessive algal growth. Submerged plants appear wilted or damaged due to chemical exposure. A pond is surrounded by cornfields and receives water from nearby irrigation ditches. After heavy rains, the pond’s surface shows a slight greenish tint, and algae begin forming small clusters near the shore. Fish and invertebrates are still present but less visible than usual. Which situation would result in eutrophication of the pond? Choose all that apply
