Water Quality Chemical Parameters Flashcardz

Front

What is eutrophication?

Back

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

Front

How do decomposers affect dissolved oxygen levels in water?

Back

Decomposers use dissolved oxygen in cellular respiration, which can decrease oxygen levels in water, especially during eutrophication.

Front

What happens to fish populations when a large amount of fertilizer enters a lake?

Back

The number of fish dying in the lake will likely increase due to decreased oxygen levels and harmful algal blooms.

Front

Define biotic factors in an ecosystem.

Back

Biotic factors are the living organisms in an ecosystem, including plants, animals, and microorganisms.

Front

What does the term 'anoxic' mean?

Back

Anoxic refers to conditions where there is no oxygen present.

Front

What is turbidity in water?

Back

Turbidity is a measure of how clear water is, often affected by the presence of suspended particles.

Front

How does high turbidity affect water quality?

Back

High turbidity often indicates a higher number of contaminants in the water, which can harm aquatic life.

Front

What role do algae play in water ecosystems?

Back

Algae produce oxygen through photosynthesis but can deplete oxygen levels when they die and decompose.

Front

What is the impact of excess nutrients in water bodies?

Back

Excess nutrients can lead to algal blooms, which can harm aquatic ecosystems and reduce oxygen levels.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which organisms convert glucose and oxygen into energy, producing carbon dioxide and water.
