Rainbow trout are found in mountain streams and are sensitive to changes in their

habitat. Which would

be the BEST description for the use of rainbow trout in water quality testing?

• biological indicator

• invasive species

• nitrates

• dissolved oxygen

What is the difference between potable water and safe water?

• potable water is safe to drink while safe water is safe to clean and shower; not to drink

• they are both the same

• safe water is safe to drink while potable water is not safe to drink

• Safe water is potable water while potable is not safe water.

contribute to excessive plant growth in a water system?

• iron and lead

• copper and zinc

• calcium and magnesium

Which water quality data most likely indicates eutrophication?

• ph level

• turbidity

• nutrient level

• temperature

How are indicator species like a warning system for bodies of water?

• They indicate when food sources are declining.

• Their illness or death indicates pollution in an aquatic ecosystem.

• They indicate when predators are reducing the numbers of a species.

• Their illness or death indicates the body of water is becoming more populated.
