Why deep-sea organisms cannot survive in conditions closer to the oceans surface.?

Deep-sea organisms are adapted to extreme conditions such as high pressure, low temperatures, and complete darkness, which are prevalent in the deep ocean. These adaptations include specialized cellular structures and metabolic processes that allow them to thrive in nutrient-scarce environments. Moving closer to the surface, they would face increased light, temperature fluctuations, and different pressure conditions, which could disrupt their biological functions and lead to stress or death. Thus, their survival is intricately tied to the unique conditions of their deep-sea habitats.
