Biodiversity

What does the word "biodiversity" mean?

Biodiversity refers to the variety of living species on Earth, including plants, animals, bacteria, and fungi. These organisms work together in an ecosystem to maintain and support all life on Earth.  It can also refer to the number of species found in a defined area, like the great state of Wisconsin! Or in your backyard, library grounds, community park, etc.
