AQUBIO X003 - Macroinvertebrate Sampling Virtual Field Trip
Plants and animals can serve as indicators of ecosystem health. Sometimes the smallest organisms are the biggest indicators of water quality. Benthic macroinvertebrates, small aquatic animals or larval forms of insects, do not have a backbone and are bottom-dwelling organisms. Because macroinvertebrates spend their entire lives in a small area, they often show the effects of environmental changes. The species and number of benthic macroinvertebrates in a habitat are indicators of the health of an aquatic ecosystem. Some macroinvertebrates are more sensitive to pollution than others; finding many of these species typically indicates better water quality. In this lesson, students will “collect” common benthic macroinvertebrates and then analyze quantitative data to determine the health of a variety of aquatic ecosystems.
Upon completion of this virtual field trip module, you will earn a contact hour certificate documenting 5 contact hours.
