Hummm....to survive on earth we need proper functioning of our different body parts nd for this we need energy in required amount...........now here a question araises how we get energy....i think u know its ans....we get energy by the oxidation of food........and for oxidation of food we need oxygen.....in absence of food (glucose),glycogen if glycogen is wholy is broken into glucose nd if glycogen is wholy used then fats and then proteins.are broken into glucose and then the same is used to produce energy...(proteins is broken then very harmfull substances are released due to which we die)...........so this takes some time while in the absence of oxygen we r unable to produce energy nd hence all of our body functions are stopped nd hence..............HUM JALDI TAPAK JAATE HAI

Why can man live without food but not without oxygen?


Food and oxygen are essential for life. The body needs food for energy and essential nutrients, while oxygen is required for respiration. However, while man can survive for some time without food, he cannot survive without oxygen for more than a few minutes. This is due to several factors, which we will explore below.


Energy Storage



  • One of the main reasons that man can survive without food for longer than without oxygen is because the body can store energy for later use.

  • The body stores energy in the form of glycogen in the liver and muscles, which can be broken down into glucose when the body needs energy.

  • In addition, the body can also use fat stores for energy, which can sustain the body for weeks or even months, depending on the person's body fat percentage.



Oxygen and Respiration



  • Oxygen is required for the process of respiration, which is how the body converts food into energy.

  • During respiration, oxygen is used to break down glucose molecules into carbon dioxide and water, releasing energy in the process.

  • If the body is deprived of oxygen, respiration cannot occur, and the body's cells cannot produce energy.



Effects of Oxygen Deprivation



  • When the body is deprived of oxygen, it can lead to a condition called hypoxia, which can be fatal if not treated immediately.

  • Hypoxia can cause a range of symptoms, including confusion, dizziness, shortness of breath, and loss of consciousness.

  • If the body is deprived of oxygen for too long, it can lead to irreversible brain damage and death.



Conclusion


In conclusion, while both food and oxygen are necessary for life, the body can survive without food for longer than without oxygen. This is because the body can store energy for later use, while oxygen is required for respiration, and the body cannot produce energy without it. Oxygen deprivation can be fatal if not treated immediately, and can cause irreversible brain damage and death if the body is deprived of oxygen for too long.
