6-3 Biodiversity The Value of Biodiversity Biodiversity: ____________________________________________________________ _______________________________________________________________________ Ecosystem Diversity _____________________________________________________ _______________________________________________________________________ Species Diversity _________________________________________________________ Genetic Diversity ________________________________________________________ _______________________________________________________________________ Biodiversity is one of Earth's greatest natural resources. Species of many kinds have provided us with foods, industrial products, and medicines—including painkillers, antibiotics, heart drugs, antidepressants, and anticancer drugs Threats to Biodiversity Human activity can reduce biodiversity by altering habitats, hunting species to extinction, introducing toxic compounds into food webs, and introducing foreign species to new environments Extinction ______________________________________________________________ _______________________________________________________________________ Endangered Species _____________________________________________________ _______________________________________________________________________ A.

Protecting an ecosystem will ensure that the natural habitats and the interactions of many different species are preserved at the same time.
