To mow or not to mow: the impact of plant communities on biodiversity
Biodiversity hotspots are regions of the Earth with a high concentration of species. Plants are often important components of biological communities because they are at the base of the food web and provide living structures for other organisms. Species richness, or the number of species in an area, is one measure of biodiversity. In this science project, you are going to test the hypothesis that c
