Complete the following paragraph to describe the relationship between biodiversity and speciation.

a. Biodiversity Correct is the variety of species present on this planet. b. Speciation Correct is the ultimate source of species diversity and occurs over time as organisms respond to changes in the environment. c. The rate of speciation and the rate of species loss Correct shapes the patterns of diversity on planet Earth. d. The process of speciation is generally a very slow Correct process, often taking millions of years to occur completely. e. If the rate of species loss is higher than Correct the rate of speciation, then there is a general loss Correct of biodiversity.
