Air SVG is a mixture of natural gases – nitrogen, oxygen, argon, carbon dioxide, water and hydrogen. It is the primary source of energy for all organisms and a guarantee of healthy growth and long life. Thanks to the air, metabolism and development take place in the organisms.
Air SVG in the life of plants and animals
Air plays a huge role in plant life. Oxygen, carbon dioxide, water vapour and soil air are fundamental components of plant growth and life. Oxygen is essential for breathing and carbon dioxide for carbon dioxide.
Oxygen is vital for all living things. Plants cannot germinate without oxygen saturation. Both roots, leaves and stems of plants need this element.
Carbon dioxide penetrates the plant through its stomata into the leaf medium, entering the cells. The higher the concentration of carbon dioxide, the better the plant life becomes.
The air SVG contributes to the microbiological processes taking place in the soil. Thanks to these processes in soil the elements necessary for a food, growth and a life of plants – nitrogen, phosphorus, potassium and others are formed.
Also air plays a special role in formation of mechanical fabrics at ground plants. It serves as their environment, protecting them from the effects of ultraviolet rays.
Air movement is important for favorable growth of plants. Horizontal air movement dries plants. And vertical promotes the spread of fingers, seeds, and regulates the thermal regime in different areas.
Animals, like plants, need Air SVG. Age, size and physical activity are directly related to the amount of air consumed.
Animal bodies are very sensitive to oxygen deficiency. Due to the lower oxygen concentration, the animals do not oxidize the proteins, fats and carbohydrates consumed. This leads to the accumulation of harmful toxins in the body.
Oxygen is needed to saturate the blood and tissue of a living being. Therefore, when there is a lack of this element in animals, breathing becomes more frequent, blood flow is accelerated, oxidation processes in the body are reduced, the animal becomes restless. Prolonged absence of oxygen saturation causes: muscle fatigue, absence of pain factor, lowering of body temperature and death.
Air SVG in human life
Air is a vital factor for man. It is carried by blood on the body, saturating every organ and every cell of the body.
It is in the air that the human body exchanges heat with its environment. The essence of this exchange is the convection of heat and moisture evaporation of their lungs.
Also air carries out protective function for an organism: dilutes chemical polluters to safe concentration. This helps reduce the risk of chemical poisoning of the body.
With the help of breathing, the body is saturated with energy. Atmospheric air consists of many elements, but its composition can change. The reason for this is the industrial and technogenic activity of a human being.
During exhalation, a person returns a quarter less oxygen inhaled and a hundred times more carbon dioxide. A person needs to breathe in 13-14 m3 of air daily. The oxygen content in a healthy person does not change much. But if this element is not enough, then there are failures in the body, the pulse rate increases.
Carbon dioxide is also important for the body, but in certain amounts. An increase in the concentration of gas causes headaches or tinnitus.
Oxygen helps the human body to get rid of carbon dioxide, which has accumulated poisons and toxins. If a person rarely goes out into the fresh air, breathes superficially, or the air contains a low concentration of oxygen, the human body can tolerate poisoning, leading to various diseases.
Environmental pollution of the atmosphere
There are a lot of substances in the world that pollute the atmosphere. These substances are produced both by man and nature itself. Sources of atmospheric pollution are: thermal power plants and heating plants, motor transport, non-ferrous and ferrous metallurgy, chemical production and others.
Human activities contribute to the emission of ash, soot and dust. Also, mineral acids and organic solvents get into the atmosphere.
Natural disasters also release various substances into the atmosphere. Volcanic eruptions, dust storms and forest fires produce dust, sulphur dioxide, nitrogen and carbon oxides.
