The stages of formation of the dead zone in water include the following:

Excessive amounts of nitrogen and phosphorous

promote aggressive biomass growth.

Surface biomass blocks sunlight and prevents

photosynthesis.

High levels of microbial activity consume

oxygen.

Surrounding water becomes hypoxic or anoxic

Root vegetation and phytoplankton decompose.

Large number of fish and other marine

life die. That is 1,2,3,4,5,6 respectively.

What is a dead zone?

A dead zone in an aquatic ecosystem is defined as the area that is characterized by presence of low levels of oxygen that occurs as a result of eutrophication.

The excessive growth of algae due to increase in the availability of nutrients in a waters body leads to the overcrowding. The death of these algae lead to decomposition reaction by bacteria which uses up the dissolved oxygen in the water body making it hypoxic.

Therefore the steps for the formation of dead zone include the following:

  • Excessive amounts of nitrogen and phosphorous promote aggressive biomass growth.
  • Surface biomass blocks sunlight and prevents photosynthesis.
  • High levels of microbial activity consume oxygen.
  • Root vegetation and phytoplankton decompose.
  • Large number of fish and other marine life die.
  • Surrounding water becomes hypoxic or anoxic.
