Biologists claim that the all-taxa survey now under way at the Great Smoky Mountains National Park in the United States will improve their ability to estimate the total number of species living today. Discuss the benefits and limitations that this data set will provide in understanding the extent of global biodiversity.

Hello everyone here we have a question saying. The Himalayan region is home to the world's tallest mountains and amazing species that are found only there. These animals include the giant panda, the wild water buffalo and the black necked crane, the only alpine crane in the world. However, the area is being threatened by deforestation. The bio geographic region with significant levels of biodiversity that is threatened by human activities is called A. The hybrid zone. Hybrid zones are regions where genetically distinct populations meet mate and produce at least some offspring of mixed ancestry. So A. Is incorrect. B biodiversity hotspot, a biodiversity hotspot is a region with a high amount of biodiversity that experiences habitat loss by human activity like the Himalayan region. And these areas are significant for biodiversity conservation. So B is correct. See watershed area, watershed area is an area of land that drains our sheds water into a specific water body. So C is incorrect. The catchment area a catchment area is the area from which rainfall flows into a river lake or reservoir. So that is incorrect. So our answer here is be biodiversity hotspot. Thank you for watching. Bye.
