A
B
Which of the following is NOT one of the three assessments performed in order to determine the overall health of a stream?
Analytical Assessment
Biological Assessment
Chemical Assessment
Physical Assessment
Biological assessments are primarily based on
level of biodiversity
health of the critters in the stream
number of trees along the stream banks
pH of the stream
Dissolved oxygen levels are one measurement taken during a chemical assessment. The percentage of dissolved oxygen is dependent on
decomposition of organisms
photosynthesis of vegetation in streams
cellular respiration of fish and aquatic life
interchange of oxygen between atmosphere and hydrosphere
Streams having an array of different velocities and depths is considered
good physical health
poor physical health
Measurement of the amount of free hydrogen ions in the water
dissolved oxygen
pH
turbidity
conductivity
Measurement of the cloudiness of water
dissolved oxygen
pH
turbidity
conductivity
The higher the level of electrical conductivity of water,
