Front

What is the effect of high temperature on dissolved oxygen?

Back

Decreased solubility of oxygen in water.

Front

Which statement about lakes is true?

Back

Lakes are more vulnerable than streams to pollutants.

Front

What is the healthiest combination of water quality parameters?

Back

Low temperature, neutral pH, and low nitrates.

Front

What is a bioindicator?

Back

An organism sensitive to its environment.

Front

What is nitrification?

Back

The process of converting ammonia to nitrite then nitrate.

Front

What happens to dissolved oxygen levels as water temperature increases?

Back

Dissolved oxygen levels decrease.

Front

What is stratification in lakes?

Back

The layering of water in lakes that can affect temperature and oxygen levels.

Front

Why are lakes more vulnerable to pollutants than streams?

Back

Lakes have longer retention times, allowing pollutants to accumulate.

Front

What is the role of nitrates in water quality?

Back

High levels of nitrates can lead to eutrophication, harming aquatic life.

Front

What is eutrophication?

Back

The process by which water bodies become enriched with nutrients, leading to excessive growth of algae.
