All Flashcards
What are the steps of eutrophication?
Nutrient overload, algal bloom, oxygen depletion, hypoxia/dead zones.
What are the primary nutrients driving eutrophication?
Nitrogen and phosphorus.
Explain the role of decomposition in eutrophication.
Decomposition of algae consumes oxygen, leading to hypoxia.
Why are non-point sources of pollution difficult to manage?
They are diffuse and widespread, making them hard to trace and control.
How do algal blooms affect sunlight penetration?
They block sunlight, reducing photosynthesis in other aquatic plants.
What is the relationship between eutrophication and biodiversity loss?
Eutrophication leads to dead zones and habitat loss, reducing biodiversity.
How does eutrophication affect water chemistry?
It can change pH, temperature, and increase CO2, leading to ocean acidification.
Describe the characteristics of a eutrophic body of water.
High nutrients, abundant algae and plants, potentially harmful algal blooms.
Describe the characteristics of an oligotrophic body of water.
Low nutrients, clear water, low aquatic life.
What is the role of bivalve mollusks in preventing eutrophication?
They filter water, removing excess nutrients and algae.
How does fertilizer use contribute to eutrophication?
Excess fertilizer runs off into waterways, providing nutrients for algal blooms.
How can stormwater facilities help prevent eutrophication?
They capture runoff, preventing pollutants from reaching waterways.
How does wise fertilizer use help prevent eutrophication?
Reduces nutrient runoff into water bodies.
How can upgrading wastewater treatment plants help prevent eutrophication?
Removes nutrients from wastewater before discharge.
How can reducing fertilizer use help prevent eutrophication?
Less nutrient runoff into water bodies.
How can implementing buffer zones along waterways help prevent eutrophication?
Vegetation filters runoff, reducing nutrient pollution.
How can promoting sustainable agriculture help prevent eutrophication?
Reduces fertilizer and pesticide use, minimizing nutrient runoff.
How can restoring wetlands help prevent eutrophication?
Wetlands filter water and remove nutrients.
How can improving animal waste management help prevent eutrophication?
Reduces nutrient runoff from farms.
How can public education help prevent eutrophication?
Increases awareness and promotes responsible practices.
How can implementing stricter regulations on industrial discharge help prevent eutrophication?
Reduces nutrient pollution from industrial sources.
