Which mechanism primarily causes an oxbow lake to eventually become a swamp?

💡 Explanation

When nutrient runoff increases, eutrophication occurs as excess nitrogen and phosphorus fuel algal blooms, leading to oxygen depletion and subsequent organic matter accumulation, transitioning the lake into a swamp. Therefore, swamp formation is sped up by eutrophication, rather than changes in water balance or chemical weathering of surrounding rock.
