Answer :
Final answer:
Oxygen, nitrate, and phosphate concentrations in the ocean decrease with increasing depth due to limited light for photosynthesis and upwelling bringing nutrients from the deep ocean.
Explanation:
To draw an ocean profile of oxygen, nitrate, and phosphate for the Atlantic and Pacific Ocean down to 4000 meters water depth, we would typically expect to see decreasing concentrations with increasing depth. As we move deeper into the ocean, less light reaches the water, leading to a decrease in photosynthesis and therefore a decrease in oxygen production. Additionally, as water moves away from the surface in a process called upwelling, nutrients like nitrate and phosphate are brought up from the ocean depths, resulting in higher concentrations at shallower depths compared to deeper depths.
