Verified step by step guidance

Understand the concept of 'dead zones': These are areas in aquatic environments with low oxygen levels, often caused by excessive nutrient pollution, leading to the death of marine life.

Identify the process of eutrophication: Eutrophication is the enrichment of water bodies with nutrients, primarily nitrogen and phosphorus, which leads to excessive growth of algae and other aquatic plants.

Recognize the role of nutrient runoff: Nutrient runoff from agricultural lands and urban areas contributes to eutrophication by introducing high levels of nutrients into water bodies.

Connect eutrophication to 'dead zones': The excessive growth of algae due to eutrophication eventually leads to oxygen depletion as the algae die and decompose, creating 'dead zones'.

Differentiate between the given reactions: Hydrolysis, nitrification, and oxidation are chemical processes, but eutrophication is the ecological process directly linked to the formation of 'dead zones'.
