What is biodiversity? What do scientists need to know to calculate it for a habitat?

What will be an ideal response?


"Biodiversity is the result of speciation and extinction occurring over time, and the result of these two processes has been the gradual increase in the number of species. No one knows how much biodiversity exists. Estimates range widely, and the upper-limit estimates keep rising. Groups especially rich in species are the flowering plants (270,000 species) and the insects (950,000 species), but even less diverse groups, such as birds or ferns, are rich with species that are unknown to most people."
