Dissolved oxygen levels can decrease due to processes like respiration by aquatic organisms, decomposition of organic matter, and insufficient mixing of water. Pollution, high temperatures, and excessive plant growth can also lead to decreases in dissolved oxygen levels in water bodies.

When daylight starts to fade why do oxygen levels go down?
Oxygen levels do not actually decrease with fading daylight. However, during photosynthesis, plants produce oxygen when exposed to sunlight. So in the absence of sunlight at night, the production of oxygen decreases. This might give the impression that oxygen levels go down when daylight fades.
How far do you need to go tell you run out of oxygen?
The distance you can go before running out of oxygen depends on factors like your level of physical activity and the volume of oxygen in your tank. On average, a scuba diver with a standard tank can go from 30 minutes to an hour at recreational depths before running out of oxygen. It is essential to monitor your oxygen levels and plan your dive accordingly.
How is there more oxygen available to breath at sea level than there is higher in the atmosphere?
At sea level, the atmospheric pressure is higher, which compresses the air and allows more oxygen molecules to be present in each breath. As you go higher in the atmosphere, the air pressure decreases, reducing the density of oxygen and making it harder to breathe in enough oxygen with each breath.
What is the numbers of electron in the outermost energy level of an oxygen atom?
An oxygen atom has eight electrons. The first electron shell can contain two electrons so that shell is filled leaving six electrons left. Since the second electron shell can contain up to eight electrons, the remaining six electrons go into the second shell. Since the second shell is the outermost shell, there are six electron's in the outer energy level.
How low can infant oxygen level go before brain damage occurs?
Brain damage can occur if an infant's oxygen level drops below 85-90%. Prolonged periods of low oxygen levels can lead to hypoxia, causing damage to the brain and other vital organs. It is important to monitor infants closely and seek immediate medical attention if there are any concerns about oxygen levels.
What does the level of dissolved oxygen go down after sunset?
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.
Why does the level of dissolved oxygen go down after sunset?
noAnswer:There are several factors that could impact the levels of dissolved oxygen in natural water during the evening and night time. None of these are over riding enough to state that the DO levels would go up or down in all situations:* Cooler temperatures would increase the solubility of oxygen in the water. Oxygen already in the water would tend to stay there. * Temperatures in the water would go down decreasing the activity of any decomposition, slowing the reduction of oxygen levels. * Plants (algae etc.) would stop producing oxygen by photosynthesis* Plants would continue their respiration and consume oxygen * Winds are often calmer in the evening reducing aeration of the water through wave action
My blood oxygen level is 57-60 is this concerning?
My dad is in the hospital right now because his oxygen level was 67%. You should seek medical attention because the low oxygen level can cause brain damage and memory loss as well as begin to shut down your organs. I pray things go well for you.
Can you ever go down a level on Moshi Monsters?
no. you cannot go down a level, but you obviously can go up. The higher you are, the longer it takes to level up. If you let your monsters bars go down, you will find it harder to level up, but don't worry. The moshi level will never EVER go down, so good luck buttercup
Is 96 low oxygen level?
If it is your oxygen level how old are you? and IRS ok its not perfect but you should be fine if it doesn't go back up to 100 go see your doctor.
What will change if you go in outer space?
Your weight Oxygen level
How can you get the oyster net in big nate poptropica?
to get the oyster net... you have to go down all the way to the right or else you might go up and get out of oxygen so the you go down and then you go down super fast and then you might run out of oxygen but you still get it
Can creatinine levels go up and down?
can creatinine level go up and down
Why is pressure on mounteverest?
bcoz when u go higher from the earth's surface the oxygen level decreases. we know that earth has a strong layer that is atmosphere so it has a level where it ends so if u go more further the oxygen level decreases!!!
Is 95 good oxygen level?
If you refer to the blood oxygen level in humans, yes, that is a good level. In that context it is given as a percentage and in the human blood where it goes from 90 to 98 normally in a healthy person
What substances let things go into and out of the cell?
Proteins made on "bound" (attached) ribosomes leave through the cell membrane, and other proteins will enter the cell.
Why air pressure is low at the top and why there is less oxygen at height?
Air has weight. The weight of all the air above pushes down, squeezing on the lower levels. Think of a column of air seven miles high, pressing down on air at ground level. We call this pressing down force " air pressure ". The amount of oxygen in the atmosphere is close to the same whether you are at 30,000 feet or down at sea level, the difference is the pressure. Humans get oxygen into their blood by breathing air into our lungs where air pressure forces it into our blood. When you go up to very high altitudes, the oxygen is still there, but there is not enough pressure to force it into our blood and we would suffer from 'hypoxia', or, a lack of oxygen.
