The purpose of this activity is to give students practice for a real BioBlitz event, conducted either locally or within a national park. Background Biodiversity refers to the diversity of living organisms and the connections between them in a given area (“BioBlitz”, 2013). Any natural area will support diverse organisms, regardless of the area’s size, including animals, plants, invertebrates, nonvascular plants, fungi, and microorganisms. All organisms need certain things in order to survive. These include food or nutrients, water, air, space to live, specific temperature ranges, etc. Differen Duration: 90 Minutes.
