Question

during hot seasons, where do fish typically move to find higher dissolved oxygen levels? deeper into cooler water closer to the shallow areas toward the waters surface just at the water surface

Explanation:

In hot seasons, water temperature rises, reducing dissolved oxygen in warmer, shallower water. Cooler, deeper water holds more dissolved oxygen. So fish move deeper into cooler water for higher oxygen levels. Shallow areas are warmer with less oxygen, and the water's surface (especially in hot seasons) doesn't have higher oxygen than deeper cool water.

Answer:

deeper into cooler water
