The correct answer is option 2: Dead Sea is called so because it does not support any aquatic life. The water of the Dead Sea is extremely saline, containing a high concentration of salt and minerals. This high salinity makes it impossible for most forms of aquatic life, such as fish and plants, to survive in the Dead Sea. Additionally, the Dead Sea has a very low level of oxygen, further making it inhospitable for aquatic life. Despite its name, the Dead Sea is not actually dead in the literal sense, as it is home to certain types of bacteria and microorganisms that are adapted to the extreme conditions. However, compared to other bodies of water, the Dead Sea has very little biodiversity.
