Scientists are interested in measuring the effect of pollution on the water quality of a stream. They will use observations of various bottom-dwelling insects, or macroinvertebrates, collected in the stream as indicators of the physical, chemical, and biological conditions within the stream. Which of the following best describes why macroinvertebrate sampling can be used to assess the overall health of a stream?

Macroinvertebrates live in an aquatic ecosystem for a long enough time to show the chronic effects of pollutants, and many tend to remain in the same area throughout their life span.

Macroinvertebrates migrate long distances to feed or reproduce, and they have a low tolerance to pollutants.

Macroinvertebrates are top predators, so they are often used in determining whether toxins will bioaccumulate or biomagnify in an aquatic environment.

Macroinvertebrates can be collected to evaluate the effect of various test parameters such as dissolved oxygen, nitrites, and pH at the time that the sample was taken.

Now click on the mid-Atlantic stream.

Where is the best place to sample from in the stream?

1

Explain why you think this is the best place to sample in the stream.

What do you use to measure a sample of water's physical properties?

1

Identify three parameters you are measuring in regards to a sample of water's physical properties.

1

How deep does the probe need to be in the water (click on the probe to submerge it)?

After you take three samples, record your average measurements of the sample of water's physical properties in the data table.
