When every single member of a species, animal or plant, dies and none are left alive anywhere in the world, then that species has gone extinct. Extinction of a species can happen for many reasons.

Because soils contain very little phosphorous: it is a major limiting factor for plant growth. Excess phosphorous is added to aquatic ecosystems by: runoff of animal w ...

Eutrophication
Eutrophication (Greek: eutrophia—healthy, adequate nutrition, development; German: Eutrophie) or more precisely hypertrophication, is the ecosystem's response to the addition of artificial or natural substances, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system. One example is the ""bloom"" or great increase of phytoplankton in a water body as a response to increased levels of nutrients. Negative environmental effects include hypoxia, the depletion of oxygen in the water, which may cause death to aquatic animals.
