We may conclude, then, that air contains some gases, water vapor and dust particles. The gases in air are mainly nitrogen, oxygen small amount of carbon dioxide, and many other gases. However, there may be some variations in the composition of air from place to place. We see that air contains mostly nitrogen and oxygen. In fact, these two gases together make up 99% of the air. The remaining 1% is constituted by carbon dioxide and a gew other gases, water vapour and dust partiicles.
HOW ODES OXYGEN BECOME AVAILABLE TO ANIMALS AND PLANTS LIVING IN WATER AND SOIL
The animals and plants living in water take in the oxygen dissolved In water.
The presence of dissolved oxygen in water can be felt by a simple experiment.
Activity: Take some water in a beaker and heat it slowly on a tripod stand . Heat it before it begins to boil. Now carefully look at the inner surface of the beaker. We see tiny bubbles on the inside. These bubbles come from air dissolved in water when we heat it, the air dissolved in it begins to escape and we see bubbles in water. The organisms that live in soil also need oxygen to respire. If we take a lump of dry soil In a beaker and add water in it, we can observe bubbles coming out of soil. This shows the presence of air in soil.
The plants and animals that live inside the soli respire in this air. A lot of burrows and holes are formed in deep soil by the animals living in the soil. These burrows also make spaces available for air to move in and out of soil. However, when it rains heavily water fills up all the spaces occupied by the air in soil. In this situation animals living in the soil have to come out for respiration .
This is why earthworms come out of soil during rainy season .
