In Rest a normal human (65 Kgs Body Weight) will need 250ml/min. of oxygen.Depending on the activity the body might consume 15 times as much oxygen as it needs in rest.
they consume 20-25 % of all oxygen used by the body at rest
A horse needs to consume at minimum 1% of it's body weight daily, but 2% is better.
Your body needs a certain amount of calories to function - let's say 2000 per day. If you consume 2000 and use 2000, your weight will be stable. If you consume 2500 per day and use 2000, you will gain weight. To lose weight, you need to use more than you consume. Say consume only 1500 per day and use 2000 and you will lose weight. To cut back on calories is good but you must also exercise more, go for a 30 minute walk a day. Walk the dog. Take up a sport.
a human breaths 20 liters / minute with oxygen being 21% of the air this means +- 4liters / min intake although a lot of the oxygen leaves our body again when exhaling (4% oxygen gets taken in by our body, and 4% extra CO2 is exhaled) this means a human body takes about 0.16liters of oxygen / minute

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.
The Dunnart is one type of marsupial mouse that can easily consume the equivalent of its own body weight daily.
This depends on body type, height and current weight.
VO2 max is a measure of the maximum volume of oxygen that an athlete can use. It is measured in millilitres per kilogramme of body weight per minute (ml/kg/min).
The elements oxygen, carbon, hydrogen, and nitrogen a comfortable 95% your body weight.
Water is not an element, it is made of Hydrogen and Oxygen. Oxygen is the most plentiful element in the human body by weight. If you go by number of atoms, then Hydrogen would be the most plentiful.
