Water Quality Testing- Aquatic Science

Front

What is eutrophication?

Back

Eutrophication is the process by which water bodies become overly enriched with nutrients, leading to excessive growth of algae and depletion of oxygen.

Front

What does 'algal bloom' refer to in eutrophication?

Back

Algal bloom refers to the rapid increase in the number of algae (plants) in water bodies, often due to excess nutrients.

Front

What is Dissolved Oxygen?

Back

Dissolved Oxygen is the amount of oxygen that is present in water, which is essential for aquatic life.

Front

Why do dead zones occur in water bodies?

Back

Dead zones occur when decomposers break down dead algae, consuming oxygen and creating areas where aquatic life cannot survive.

Front

What is salinity?

Back

Salinity is the measure of the amount of salt dissolved in water.

Front

What does pH measure?

Back

pH measures how acidic or basic a solution is.

Front

What are nitrates and phosphates?

Back

Nitrates and phosphates are nutrients that can lead to eutrophication when present in excess in water bodies.

Front

How does temperature affect water quality?

Back

Temperature affects the solubility of oxygen in water; warmer water holds less oxygen, impacting aquatic life.

Front

What is the significance of turbidity in water quality?

Back

Turbidity measures the clarity of water; high turbidity can block sunlight and affect photosynthesis in aquatic plants.

Front

What role do decomposers play in aquatic ecosystems?

Back

Decomposers break down dead organic matter, recycling nutrients back into the ecosystem but can also deplete oxygen.
