All Flashcards
How can bivalve mollusks help protect the environment?
They filter water, removing excess nutrients and improving water quality.
How do stormwater facilities help prevent eutrophication?
Capture runoff, preventing pollutants from reaching waterways.
How does wise fertilizer use promote sustainability?
Reduces nutrient runoff, preventing eutrophication and water pollution.
What are the steps of eutrophication?
Nutrient overload -> Algal bloom -> Oxygen depletion -> Hypoxia/Dead zones.
What are the environmental consequences of fertilizer runoff?
Eutrophication, algal blooms, dead zones, and loss of aquatic life.
What is the effect of algal blooms on aquatic ecosystems?
Blocks sunlight, depletes oxygen, and can release toxins, harming aquatic life.
What are the effects of excess CO2 in water due to eutrophication?
Ocean acidification, harming marine organisms and ecosystems.
What are the consequences of dead zones?
Loss of biodiversity, fish kills, and uninhabitable areas for aquatic life.
What is the impact of wastewater discharge on water bodies?
Introduces excess nutrients, leading to eutrophication and water pollution.
What is the effect of decreased dissolved oxygen?
Aquatic life dies due to lack of oxygen.
What are the effects of agriculture runoff?
Fertilizers and animal waste runoff.
What are the effects of industrial activity?
Wastewater discharge.
What are the effects of population growth?
Increased sewage and waste.
What are the effects of algal toxins?
Harming humans and animals.
