What is biotic interchange?

Answer 1

Biotic interchange refers to the process through which species migrate between different ecosystems or geographic regions, leading to the exchange of flora and fauna. This phenomenon typically occurs when barriers such as land bridges or changes in climate allow for the movement of species. It can significantly impact biodiversity, ecosystem dynamics, and evolutionary processes, as new species may compete with or displace existing ones. Historical examples include the Great American Interchange, where species migrated between North and South America.
