What population conditions make an extinction vortex likely to occur?

What population conditions make an extinction vortex likely to occur?

These events can include rapid loss of population size due to disease, natural disasters, and climate change. Habitat loss and/or habitat degradation can also kick start an extinction vortex. Other factors include events that occur more gradually, such over-harvesting (hunting, fishing, etc.), or excessive predation.

Eutrophication is often caused by excess limiting-nutrient runoff from agricultural fields into aquatic ecosystems.

What does excessive algae on water cause?

Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle. Significant increases in algae harm water quality, food resources and habitats, and decrease the oxygen that fish and other aquatic life need to survive.

Which type of pollution is caused by the use of excess nutrients and pesticides?

Nutrient pollution is the process where too many nutrients, mainly nitrogen and phosphorus, are added to bodies of water and can act like fertilizer, causing excessive growth of algae. Nutrients can run off of land in urban areas where lawn and garden fertilizers are used.
