No, running water typically has more oxygen than standing freshwater. This is because running water constantly churns and aerates, allowing for better oxygen exchange with the atmosphere. Standing freshwater can become stagnant and depleted of oxygen, especially in warm conditions or with high levels of organic matter present.
Dissolved oxygen levels are lower in saltwater due to the higher salinity, which decreases the solubility of oxygen. Additionally, the solubility of gases decreases as water temperature increases, which can further reduce dissolved oxygen levels in saltwater compared to freshwater.
No, running typically has a higher oxygen demand than walking due to the increased intensity and energy expenditure involved in running. When running, the body requires more oxygen to fuel the increased muscle activity and higher heart rate compared to walking.
Oxygen is most likely to form the oxide ion (O2-) by gaining two electrons.
Dissolved oxygen is likely to be lowest in water bodies that are polluted, have high temperatures, low levels of vegetation, or are highly stratified. These conditions can reduce the amount of oxygen that can dissolve in the water, leading to lower levels of dissolved oxygen.
No, aluminum and oxygen are unlikely to form a covalent bond. They are more likely to form an ionic bond, where aluminum loses electrons to oxygen to form aluminum oxide.
Running water typically has more oxygen than standing water because the movement of the water helps to aerate and oxygenate the water. Freshwater usually contains more oxygen than saltwater due to differences in solubility and temperature affecting oxygen levels.
oxygen(O2)
There is no set amount of light or of oxygen in fresh water.
Most likely it is a dirty or malunctioning oxygen sensor located on the manifold.
Dissolved oxygen levels are lower in saltwater due to the higher salinity, which decreases the solubility of oxygen. Additionally, the solubility of gases decreases as water temperature increases, which can further reduce dissolved oxygen levels in saltwater compared to freshwater.
The type of standing water habitat you are referring to is likely a bog. Bogs are characterized by acidic soil, low oxygen levels, and slow decomposition rates, leading to the accumulation of peat moss.
Freshwater typically has a greater concentration of dissolved oxygen compared to saltwater because oxygen dissolves more easily in freshwater due to its lower salinity. Ocean water is less oxygenated because it has a higher concentration of salts, which can make it more challenging for oxygen to dissolve.
NO!
No, Earth is not running out of oxygen. The Earth's atmosphere is made up of about 21 oxygen, which is constantly being replenished through processes like photosynthesis by plants and algae.
Freshwater marine organisms obtain oxygen through diffusion across their body surface or through specialized respiratory structures like gills. They extract dissolved oxygen from the water around them to support their metabolic processes. Some organisms, like fish, have a more efficient respiratory system to extract oxygen from water.
Factors that limit aquatic life are - Temperature - Access to sunlight - Dissolved oxygen concentrations - Availability of nutrients, such as nitrogen and phosphorus
Because salt water has higher density
