All Flashcards
What are the steps of eutrophication?
Nutrient overload -> Algal bloom -> Oxygen depletion -> Hypoxia/Dead zones.
What are the effects of agricultural runoff on aquatic ecosystems?
Nutrient pollution leading to eutrophication, algal blooms, and dead zones.
What is the effect of untreated wastewater discharge on water quality?
Introduction of pathogens and nutrients, leading to eutrophication and health risks.
What are the effects of algal blooms?
Blocking sunlight, oxygen depletion, and potential release of toxins.
What are the effects of hypoxia in aquatic ecosystems?
Fish kills and loss of other aquatic life.
How does population growth contribute to eutrophication?
Increased sewage and waste, leading to higher nutrient levels in waterways.
What is the impact of eutrophication on drinking water sources?
Water becomes unsafe for consumption due to toxins and changes in water chemistry.
What is the impact of eutrophication on irrigation water?
Water quality decreases, potentially harming crops and soil.
What is the effect of climate change on eutrophication?
Increased water temperatures can exacerbate algal blooms.
What are the effects of fertilizer overuse?
Nutrient runoff leading to eutrophication in nearby water bodies.
What is the impact of deforestation on eutrophication?
Increased erosion and runoff, carrying nutrients into waterways.
Define eutrophication.
Excessive nutrient enrichment in a body of water, leading to overgrowth of plants and algae.
Define point source pollution.
Pollution from a specific, identifiable location.
Define non-point source pollution.
Pollution from diffuse, widespread sources.
Define algal bloom.
Rapid overgrowth of algae in a body of water.
Define hypoxia.
Low dissolved oxygen levels in water.
Define dead zone.
Area in a body of water with insufficient oxygen to support most aquatic life.
Define oligotrophic.
A body of water with low nutrient levels.
Define mesotrophic.
A body of water with moderate nutrient levels.
Define anthropogenic.
Caused by humans.
Define cultural eutrophication.
Eutrophication accelerated by human activities.
