Please Select the Correct Sequence of Steps Involved in the Creation

Please select the correct sequence of steps involved in the creation of a dead zone in a water body.
1) Heterotrophic microbes metabolize the organic compounds synthesized by primary producers.
2) Water becomes hypoxic and toxic algal blooms may occur; animals in the area either flee or die.
3) Water accumulates nutrients as it runs through agricultural, industrial, and urbanized regions.
4) Dissolved O2 is consumed by metabolic activity of heterotrophs.
5) Excess nitrate and phosphate in nutrient-rich water causes algae and cyanobacteria to flourish.
