Показать описание
Biodiversity encompasses genetic, species, and ecosystem diversity. Biodiversity is dynamic and changes over time, influenced by speciation and extinction events. However, human actions—such as climate change and overexploitation—are increasing extinction rates. As extinction rates increase, ecosystems experience a loss in biodiversity.
Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere. We offer quizzes, questions, instructional videos, and articles on a range of academic subjects, including math, biology, chemistry, physics, history, economics, finance, grammar, preschool learning, and more.
