Temporary dead zones are short lived dead zones lasting hours or days. Seasonal dead zones are annually occurring, typically in warm months of summer and autumn. Diel cycling hypoxia is a specific seasonal dead zone that only becomes hypoxic during the night
The dead algae biomass is decomposed by bacteria that also consume large quantities of oxygen, which they obtain from the water, creating a "dead zone" without oxygen for fish or other organisms. A classic example is the dead zone in the Gulf of Mexico due to agricultural runoff into the Mississippi River .
This decomposition process consumes oxygen, depleting the supply for other marine life and creating what is referred to as a "dead zone." Dead zones are hypoxic, meaning the water has very low levels of dissolved oxygen. This kills off marine life or forces it to leave the area, removing life from the area and giving it the name dead zone.
Every spring, an area appears when the water doesn't have enough oxygen to support fish and other marine life.
A dead zone is an area of water that cannot sustain aquatic life because the oxygen levels are low or depleted. The scientific term for a dead zone is called hypoxia, which in Latin means "too ...
Ecological death is the inability of an organism to function in an ecological context, leading to death. [1] This term can be used in many fields of biology to ...

A biological rule which states that two species cannot coexist in the same environment if they are competing for exactly the same resource, often memorably summarized as "complete competitors cannot coexist". coniferous forest One of the primary terrestrial biomes, culminating in the taiga. conservation biology The study of Earth's biodiversity with the aim of protecting and ...
Dead phytoplankton and other organisms sink to the bottom giving rise to large numbers of decomposers due to increased food supply (dead organisms, phytoplankton). Due to the increased number of decomposers that use more oxygen, fish and shrimp at the lower layers of the ocean become oxygen-starved, resulting in the creation of hypoxic zones .
