On this field trip, students collect and examine data to understand how availability of resources affects populations of microorganisms in the desert. Students observe desert potholes and learn about strategies organisms use to survive in these diminishing ecosystems. Students also examine desert lichens to see how the orientation of rocks affects a lichen’s ability to thrive.
