How does nutrient enrichment cause chemical and environmental change that results in major shifts in animal life?

Nutrient enrichment had definitely impact animal life and leads to destruction of their natural habitat and curtails growth.

Explanation: The nutrients that are infused into the soil to enrich it can hamper a lot of on the surface level as well the organisms which are affected eventually.

The upstream of the nutrients reaching the coastal ecosystems which leads to

The impacts that it will have on

The prediction is gloomy as over the years it could lead to major shifts in animal life and have a larger impact on the environmental change that would be irreversible.

The nitrogen levels are peaking which is over-enrichment and more susceptible environments are bearing the and results show that now dead zones are being identified.    

the oxygen levels get lowered resulting in the death of fish

cellular respiration oxidizes food into energy in the form of atps.

glycolysis (6 c hexose) > 2x atps are used > 6c hexose biphosphate > 2 x 3c triphosphate >

2 x 3c pyruvate (2x nadh produced from nad) and (4x atp produced)

pyruvate actively pumped mitochondrial matrix.
