What term describes the area where two different terrestrial biomes meet?

The term describing the area where two different terrestrial biomes meet is ecotone. An ecotone is a transitional zone that exhibits characteristics of both adjacent biomes, meaning it includes species and environmental conditions from both ecosystems. This biodiversity can often result in unique ecological communities that thrive in these areas.

Ecotones are important for studying interactions between different biomes and can serve as critical habitats for various organisms that rely on the resources available from both adjacent environments. This concept underscores the complexity and interconnectedness of ecological systems and highlights the significance of biodiversity in transitional areas.
