Eutrophication Quiz

Eutrophication is an environmental issue that affects both coastal and inland areas. It begins with the introduction of nutrients into water bodies, leading to excessive algae growth. This growth blocks sunlight, causing plant death. As algae die, bacteria consume them, depleting oxygen and releasing carbon dioxide, which harms aquatic life. Effective agricultural and waste management practices can help mitigate this problem.

Why should Eutrophication matter to everyone, regardless of their proximity to the ocean?

• It only affects marine life.

• It is a problem exclusive to agricultural areas.

• It starts where people live and impacts resources used by everyone.

• It only affects people living near the ocean.

What is the initial cause of Eutrophication in lakes and oceans?

• Overfishing

• Climate change

• Deforestation

• Nutrient influx

What happens to plants when algae blocks sunlight?

• They produce more oxygen.

• They turn into algae.

• They die.

• They grow faster.

What do bacteria do when algae and plants die?

• They digest the dead plants, using up oxygen and releasing carbon dioxide.

• They produce more sunlight.

• They stop functioning.

• They turn into fish.

What is a key practice to protect marine resources from Eutrophication?

• Increasing fishing activities

• Building more dams

• Introducing more algae

• Sound agricultural and waste management practices
