Air
Air is very important component of our environment. No living organisms can live without air. All the organisms requires oxygen for respiration. Carbon dioxide is used by green plants to make food by the process of photosynthesis. Nitrogen is very important for plants. Air is the mixture of various gases like oxygen, nitrogen, carbon dioxide, helium, neon etc. Our earth is enveloped by a thick layer of air called atmosphere. The composition of various gases in air are given below,
AirComposition (%)Nitrogen78%Oxygen21%Carbon dioxide0.03%Neon0.0018%Helium0.0005%
As the population of the world is increasing, the air is getting polluted day by day due to the human activities. Various gases released from the industries like sulphur dioxide, carbon dioxide etc. causes air pollution. Air pollution is also caused by mining activities, burning of fossil fuels, different types of chemical fertilizers etc. Deforestation and excessive burning of fossil fuel increases the amount of carbon dioxide in air. We should not pollute the air, it not only affect the humans but also affect all the living organisms living on this earth.
Water
Water covers about 71.4% of part of the earth. About three by four part of the earth is covered by water. The molecular formula of water is H2O. Water is a molecule made up of two molecules of hydrogen and one molecules of oxygen. Rain water, surface water and underground water are the main three sources of water found in earth. Other common sources of water are stream, river, lake, sea etc.
Biotic Components
Biotic components are the living things of the environment. Plants, animals, and microorganisms are the biotic components of the environment. Biotic components of an environment are classified into three groups.
