How the sun is keeping us alive.

Every soul needs energy to survive, to survive. I need energy for what I see on my mobile screen, I need energy for sitting comfortably under a fan, I also need energy for fashioning colorful clothes. Even the survivors need energy. All the energy needed to survive and thrive comes from the sun.

Maybe I get energy by eating food but the source of that energy is not food, the sun. Maybe I am charging my mobile from the electricity of hydropower or thermal power plant, but the source of that energy is not the power plant, the sun. Not only this, the sun is behind almost all the energy of the earth.

An unimaginable amount of energy is generated through nuclear fission in the Sun's chest. A small portion of them reach the earth through radiation. The earth's environment and biodiversity are based on this little energy. Almost all living things on earth use the energy of the sun. How ?

Let us first consider the plants. Plants make their own food from sunlight. Plant food is produced by the reaction of sunlight with atmospheric carbon dioxide and minerals absorbed from the soil through the roots.

The leaves of the plant do this job of making food. The processes that take place in the leaves are like a huge factory made up of thousands of solar panels. The leaves of the tree are flattened so that the sun's energy can be harnessed. When flattened, its area increases and light falls on more places. More light means more energy and food production.

The different types of food (basically sugar) produced in the leaves go through different processes throughout the body of the plant. Different parts of the body again make starch from sugar. As energy it is again more convenient than sugar. The animals of the world survive by eating them as food.

When a herbivorous animal, such as a deer or a rabbit, eats a plant, the energy of the plant also enters their body. Strengths are used to gather food, to mate, to run in danger, to fight with others, and so on. Although collected from plants, the original source of these energies is the sun.

Carnivores again eat herbivores. As a result, the energy of herbivores is being transferred to carnivores. This power is also used by carnivores to fight, run, maneuver, climb trees, etc. Although a few extra steps are coming up; But here also the sun is the main source of energy.

The sun is also the main source of energy for small animals that live in carnivores. When an organism dies, it decomposes in the soil. Sometimes their bodies are eaten by garbage-eating animals. An example of such a waste-eating animal is the beetle. Bacteria or fungi can also eat away at the carcass. Here again, the sun is the main source of energy.

We use wood or coal or oil for fuel. The sun is behind all of them. Trees grow or become wood using direct sun energy. Occasionally some trees and plant material are converted to coal. These are also great as fuel. The main force here is the sun. Fuel oil (fossil fuel) is made in the same process. Today's cars, horses and motors use this oil. Modern machine civilization is standing on these. Here too the primary source of energy is the sun.

Thermal power plants use the chemical energy of the fuel gas and the hydroelectric power plants generate electricity using the stored energy (potential energy). Here too the sun is the main source of energy.

Fuel gas is produced by storing solar energy like oil. That's fine. But how does the sun come to the stored energy of water? In hydroelectric power plants, water is mainly dammed and pumped from top to bottom. When something falls from above, the force of gravity creates kinetic energy between them. It is specially processed to generate electricity. Now the question is who is taking the water up? If the water had not risen, we would not have got this energy.

The sun is basically raising the water. In a very nice way called water cycle, the sun converts water into steam and floats it in the air. They fall as rain in the highlands. They come down the river slowly. On the way, some of the people use some of the energy stored in the dam for their own work.

If you say so, it will not end. The hand of the sun is in everything, no matter where we look around. Soil, water, leaves, vines, wood, coal, oil, paper, cloth, furniture, heaters, fans, etc., all contribute to the sun, the presence of the sun. We are indebted to the sun for every minute we live on earth. Not only us, but all living beings on earth are directly or indirectly indebted to the sun.

The sun is giving us so much, it is feeding and keeping us alive, we should do more research on the sun. Breaking the mystery of the sun, bringing out more and more energy from the sun. From time to time scientists have sent various missions to understand the sun. This time a spacecraft is sending the sun to rotate from very close to the sun. Name Parker Solar Probe. When it rotates around the sun and sends a lot of information about the sun, many secrets of the sun will be revealed to us. If you know the secret of the sun well, even a small debt of the sun will be repaid.
