Which technology do environmental scientists use to track the movements or polar bears and other vulnerable populations? a) geographic information system(gis) b)environmental dna(edna) surveillance c) global positioning system(gps) d) unmanned aerial system (uas)

c.  Global Positioning System(GPS)

Explanation:

Global Positioning Stem (GPS) collars have been great tools for monitoring the movement of animal populations in vulnerable situations, such as polar bears that are at risk of extinction.
