Water has always been two parts hydrogen and one part oxygen.
The size of the aquarium and the number of fish living in the aquarium determine the amount of oxygen that is needed. The temperature of the water also plays an important role to determine oxygen needs of fish. If the water is above 80 degrees, the need for oxygen increases.
the level of oxygen dissolved in the water.
Oxygen partially dissolves in water. Respiratory systems of aquatic animals are adapted to get this dissolved oxygen. They have gills for respiration.
Three examples of abiotic factors in the Chicago River are water temperature, pH levels, and dissolved oxygen levels. These factors can have a significant impact on the health and ecosystems of the river.
fishes take in water and remove oxygen from it.....thats how they breathe....
Electrolysis separates water into its original components: oxygen and hydrogen.
You can control the oxygen through aeration
Water that has been exposed oxygen typically contains 2-3 millimole of oxygen.
Hypoxia is a deficiency of oxygen in either the fish or water itself. Water naturally has a level of oxygen dissolved in itself. That is the oxygen that fish take in through the gills. This level of oxygen in clean pure water is about 8 ppm. In the summer more algae grows in the water due to favorable conditions. This algae consumes oxygen from the water. Also, in the summer the water temperature increases. Oxygen has a lower solubility in water as the temperature increases. Therefore the level of oxygen in the water will decrease slightly as the water temperature increases. These are just a few common reasons. Every water body is certainly different.
It should be 0.
It may or may not, it depends mostly on the level of oxygen in the water. Oxygen depleted water actually preserves wood almost completely.
The oxygen level varies in different bodies of water because some bodies of water are warmer than others therefore,.. the more hot the less oxygen because the particles will begin to die as the water gets hotter but this is how it becomes a compressed gas ...
The concentration of oxygen in waters decreases.
The level of dissolved oxygen in water can be influenced by temperature (warmer water holds less oxygen), water flow and turbulence (increased mixing allows for more oxygen absorption), and the presence of aquatic plants and algae (which can produce oxygen through photosynthesis). Pollutants like nutrients and organic matter can also lower dissolved oxygen levels by promoting algal blooms and microbial activity that deplete oxygen.
Increased level of nutrients result in growth of algae in the water.These algae use up all the oxygen in water and form a layer on the water not allowing oxygen to enter.Therefore the aquatic animals die because they don't get oxygen.
The level of dissolved oxygen in water can decrease after sunset due to the lack of photosynthesis by aquatic plants. Without sunlight, plants stop producing oxygen through photosynthesis, while organisms in the water continue to consume oxygen through respiration, leading to a decrease in dissolved oxygen levels.
Oxygen in water exists as dissolved oxygen molecules, which are crucial for aquatic organisms to survive. Oxygen can be absorbed into water through diffusion from the atmosphere or by photosynthesis from aquatic plants. The level of dissolved oxygen in water is influenced by factors like temperature, pressure, and the presence of organic matter.
