Question

We can survive for some time without air but we cannot survive even for a few minutes without food. Correct the statement if wrong.

Answer 1

Air:

1. Air is the basic building block, without which life itself would not exist. Air is present in the lower region of the atmosphere called the troposphere.
2. It is a mixture of gases composed of nitrogen, oxygen, carbon dioxide, and other traces of gases.
3. It is an inexhaustible natural resource.
4. Air is the constant pressure we feel around us but can never see. The observable effects of air can be seen in nature, through the swaying of plants and trees.
5. We all need oxygen to breathe. Animals that live on land and even animals that live in water need oxygen to survive or they would perish.
6. Bubbles in water occur only because the low concentration of air is trapped in the small bubbles.
7. Plants also consume oxygen, but their consumption is much lower than their output. Thus, the net effect is that they add oxygen to the atmosphere.
8. If there is no air means no oxygen. If there were no oxygen molecules in the air, there would be fewer particles for light to emit.
9. All plants and animals need oxygen to carry out various metabolic activities. Without oxygen, we cannot breathe and life on Earth will end.

Food:

1. Humans can survive without food for days and for food glycogen can be used.
2. When our body stops getting the food, it has to live on the stored sugars. The liver and muscles store glucose which is the main source of fuel in the form of glycogen.
3. This glycogen can then be converted to glucose
4. Experts believe that the human body can survive without food for up to two months.
5. This is not the first example of people being independent for a long time.

Given statement - We can survive for some time without air but we cannot survive even for a few minutes without food.

Correct answer - 'We can survive for some time without food but we cannot survive even for a few minutes without air.
