what happens when water temperatures drop in the ocean?
concentration of dissolved nitrogen decreases
concentration of dissolved nitrogen increases
concentration of dissolved oxygen decreases
concentration of dissolved oxygen increases

Explanation:

• The bathypelagic zone (1000 - 4000 meters deep) has no sunlight, so it's called the midnight zone.
• For water temperature and dissolved gases: Generally, as water temperature drops, the solubility of gases like oxygen increases. Nitrogen is less relevant in this context compared to oxygen in terms of typical ocean - related discussions about temperature - gas solubility relationships.

Answer:

• First question: completely absent of sunlight, this zone is referred to as the midnight zone
• Second question: concentration of dissolved oxygen increases
