Neither. A non-metal element has no charge, which would be required for attraction.
When someone mentions water polarity, they are talking about the intermolecular properties of water. Water is a polar-covalent bonded molecule which means that even though the hydrogens are sharing electrons with the oxygens, the electrons will be attracted slightly more to the element with the bigger nucleus.
Antarctic waters are higher in oxygen content than are other oceans. This means that oxygen is more freely available to these animals in the Southern Ocean.
poor in oxygen and rich in carbon dioxide

Two primary sources of oxygen for the upper waters of the ocean are photosynthesis by phytoplankton and the exchange of gases with the atmosphere. Phytoplankton, which are microscopic marine plants, produce oxygen during photosynthesis, significantly contributing to the ocean’s oxygen levels. Additionally, oxygen from the atmosphere dissolves into the ocean’s surface waters, particularly in areas with strong winds or waves that enhance gas exchange. Together, these processes sustain the oxygen levels necessary for marine life.
Water vapor is invisible water (kind of like mist) that floats around in the air.
because it has oxygen and reused by other aquatic organisms
Oxygen. They use their siphon-like snorkel tail to get oxygen from the air, as it is not in the stagnant waters in which they dwell.
Compound. H2O contains 2 elements. Hydrogen, of which there are 2, and Oxygen.
== == "Turning Over" refers to the phenomena when the warm surface water (which is Oxygen Poor) is driven downward (usually by a cold hard rain after a long drought) and the colder oxygen rich waters are forced closer to the surface. Fish instinctually move to lower water depths to find more oxygen, and when the water has turned over, they find oxygen poor waters and can die of asphyxiation. Turnover does in fact refer to a mixing of warm surface waters and cold bottom waters, but actually, it is the surface waters that are oxygen rich, and bottom waters which are oxygen poor. In a lake, for example over the course of a long summer, sunlight will penetrate the surface waters, resulting in natural production of algae (phytoplankton). The phytoplankton are responsible for most of the oxygen in a lake. But as the algae becomes more productive, it shades out the lake, preventing sunlight from penetrating deeply. From the surface of the water down to the point where only the tiniest bit of light remains is called the photic zone. It is ONLY in this zone that photosynthesis can occur, and therefore oxygen production. In the bottom waters, where there is no sunlight, there is no photosynthesis and therefore no oxygen production. Furthermore, the sunlight is the only natural source of heat. So the photic zone becomes warmer as the summer goes on, while the bottom waters, which are not sunlit, stay cool. Warmer water is less dense than cold water and so the warm water floats on top of the cold water. This is called thermal stratification. So when there is a cold hard rain at the end of a long summer, the cold rain falls into the surface waters, cooling it down. When surface waters get close enough to the temperature of bottom waters, the water column will become mixed, resulting in turnover. So the short answer to your question is, turnover is NOT related to fishing. LOL.
Ponds and lakes typically undergo turnover in the fall and spring. In the fall, cooling surface waters sink and mix with deeper, oxygen-rich waters. In the spring, warming surface waters mix with cooler, nutrient-rich waters.
Bottom waters of a pond refer to the water located at the lowest level of the pond, closer to the sediment or substrate. This water tends to be cooler, denser, and may have lower oxygen levels compared to the surface waters. Organisms that live in or interact with the bottom waters are adapted to these specific conditions.
