What is the role of the Sun for living organisms on our planet?

The sun is an irreplaceable source of energy and life on our planet. Without sunlight, the life of living beings on the planet would not be possible. Plants use solar energy to produce oxygen. People use the sun to get electricity, energy, water. Without sunlight, the natural circulation of water in nature would not be possible, without which living beings are also unable to survive. The sun plays a huge role in the life of all life on earth. Even being in the sun has a positive effect on well-being. The sun’s rays are capable of killing some bacteria. If the Sun did not exist, then the Earth would plunge into eternal darkness, permafrost and simply would not be suitable for the life of living beings.
