Question

provide evidence and reasoning to support your claim. claim a evidence - nutrient runoff from agricultural land causes high dissolved oxygen levels in the gulf of mexico. - nutrient runoff from agricultural land contributes to hypoxic conditions in the gulf of mexico. reasoning

Explanation:

The first piece of evidence is incorrect as nutrient runoff typically causes eutrophication, leading to algal blooms. When these algae die and decompose, oxygen is consumed, resulting in low - dissolved oxygen levels (hypoxia) rather than high dissolved oxygen levels. The second piece of evidence is correct as nutrient runoff does contribute to hypoxic conditions in the Gulf of Mexico due to the process of eutrophication.

Answer:

The claim is about the impact of nutrient runoff from agricultural land on the Gulf of Mexico. The first evidence statement is false and the second is true. Nutrient runoff actually causes hypoxic (low - oxygen) conditions, not high dissolved oxygen levels. The reasoning should explain how nutrient runoff leads to eutrophication, algal blooms, and subsequent oxygen depletion during decomposition of the algae, contributing to hypoxic conditions in the Gulf of Mexico.
