What is oxygen sag?

Oxygen sag is a dip in the amount of dissolved oxygen in a body of water. This can be caused by several things, ranging from a drop in water flow to an increase in waste in the water. Occasionally when waste is introduced into a body of water, bacteria will begin to consume the waste. As they consume the waste, the bacteria use up oxygen, causing the overall amount of oxygen in the water to drop. In some cases, the waste itself will consume oxygen without an bacteria. Oxygen sag can lead to massive die-offs of oxygen-breathing aquatic creatures, such as fish, crustaceans and mollusks.


Why do you need oxygen and hydrogen in your body?

Carbon and oxygen atoms are plentiful. However, because such a huge percentage of your body is water and because carbon atoms are always associated with hydrogen atoms in living species, by a long way, HYDROGEN atoms are the most plentiful in a living body.

What is called the Ratio between oxygen uptake and oxygen usage?

The ratio between oxygen uptake and oxygen usage is called the respiratory exchange ratio (RER). It is a measure of the ratio of carbon dioxide produced to oxygen consumed during metabolism. This ratio can vary depending on the type of fuel being used by the body for energy.


How does oxygen enter your body?

Oxygen (O2) enters your body through breathing air, which contains oxygen in it. This oxygen goes into your lungs where it is put into the bloodstream, supplied to cells in your body, returned to the lungs as carbon dioxide (CO2), and exhaled through the lungs.

What carries food water and oxygen to the body cell?

The circulatory system, which includes the heart, blood vessels, and blood, carries food, water, and oxygen to body cells. Oxygen is carried by red blood cells, nutrients by plasma, and water is distributed throughout the body.


How do octopuses get there water?

An octopus take in water and removes oxygen from it. Then it sends the water out of its body through a short funnel. When it gets scared it shoots the water out in a fast jet. It is called Jet Propulsion.


Why does weakness result from diet lacking iron?

Iron deficiency in the body causes anemia. Weakness or fatigue results from the lack of iron because the body does not get enough oxygen-rich blood.


What does decaying matter in water bodies cause?

Decaying matter is natural in a body of water, it is natural in any environment. However a large amount of decaying matter in a body of water could lead to a dead zone. This is because if there is a disruption in the food web of that body of water it could kill many organisms. If many animals die, the decaying takes more oxygen out of the water than can be replaced and you are left with a body of water that has no oxygen called a dead zone.


Is it true the water in the body distributes oxygen coming from the lungs?

As far as I know, it is the blood of your body that carries oxygen to all of your body parts.


What body compound would have much of the hydrogen and oxygen?

Water (H2O) would have much of the hydrogen and oxygen in the body.


How is temperature related to the levels of dissolved oxygen in a body of water?

Temperature and dissolved oxygen levels in water are inversely related. As water temperature increases, the amount of dissolved oxygen decreases. This is because warmer water holds less oxygen than cooler water. Therefore, higher temperatures can lead to lower oxygen levels in a body of water, which can impact aquatic life.


What does the body need to survive?

The body needs water, food, oxygen, and shelter to survive. Water is essential for hydration and bodily functions, food provides energy and nutrients, oxygen is needed for respiration, and shelter protects the body from environmental hazards.


How can a body of water can be depleted of its oxygen?

Water can be depleted of it's oxygen by a number of different ways. Short of putting the water in a vacuum and "sucking" the dissolved oxygen out, oxygen-breathing organisms such as fish take oxygen from the water through respiration, for example. It is unlikely a large body of water to become completely deoxygenated due to the presence of photosynthetic aquatic organisms (plants) and the fact that oxygen is also dissolved in the water at the water's surface.
