The sun is our daily source of daylight. Sunlight keeps many plants alive by supporting photosynthesis process and is a major source of Vitamin D for humans. It is around sun, our earth orbits because of sun's gravitational pull. Sunlight helps us to see things because our eyes can see only when light strikes a particular thing and reached our eye. Had sun not been here we would have ended up on depending artificial light always and complete darkness in places where artificial light could not be made available. Visit Importance of Sun and Details regarding Sun.
1.the sun keeps the earth going without it we would not live 2.without the sun plants would not be able to grow and plants cause oxygen so without plants there would be no earth 3.we would not be able to eat foods that grow on a farm (most foods =vegetables)
There are myriad of benefits that we human beings are drawing from the sun and its importance can not be ignored for our survival. It is the sun that decides in which area of the earth people should stop working and which area people should start their day, though with the advent of electric light this situation is being changed to some extent.
The sun is also a major form of energy for the livings beings on earth and it gives us vitamin D also which is considered vital for the survival of people. And in recent years the effort to tap the power from the sun is also being taken very seriously. Though this method is extremely costly, the efforts are there to make it cost effective so that the energy source can be tapped for the benefits of the people.
Humans need sunlight for the production of Vitamin D, which enables to body to absorb calcium to build strong bones and teeth. Without sunlight we would have serious bone problems and diseases such as Rickets.
The body has a biological clock which involves many of the internal physiological systems to keep in tune with the rhythms in nature, most importantly, the cycles of night and day. This internal biological clock is regulated by the body’s circadian rhythms, in response to both internal and external stimuli, like sunlight, which is believed to be very important in synchronizing the body’s circadian rhythms and ensuring that the body functions properly. Our daily habit of waking up in the morning and sleeping at night is one of the most important products of circadian rhythm.
When the body does not get enough sunlight because the person has been confined to the hospital for a few weeks or has been stuck inside the house for days due to bad weather, the brain will undergo changes that may eventually result in negative moods. In addition, the hibernation hormone, melatonin, will increase with decreased light, which will eventually lead to a feeling of tiredness.
The body has other internal clocks which work both independently and together to keep the body running properly, controlling temperature and the release of hormones. These clocks include the brain, lungs, liver, heart, and skeletal muscles.
The sun is important to us because we need sun in our everyday life to live. Our sun's warmth keeps us humans warm and plants and vegetation need the sun to warm them too.
The sun is essential for live on this earth. We need the sun to warm the earth so the plants will grow and give them light so they can develop. The sun regulates night and day. The sun evaporates the water to give us rain for the plants. Without this food and water we would die.
If there was no sun there would be no pants and trees.Without plants and trees there would be no oxygen.No oxygen mean nothing can live.Everything and one would die.
The sun is important because it helps us be here today if there were no sun the would be no earth and that mean there would be no us. Also if there were no sun the earth would spin off its orbit in to outerspace
Our Sun's primary medium in sustaining life on Earth is through photosynthesis to fuel the Food Chain and through evaporation and precipitation in the Water Cycle. Our Sun also provides adequate temperatures for life as we know it to thrive. Many animals are also cold-blooded and regulate their body temperature with the warmth of sunlight and most life-forms maintain a vision-based perception of reality only possible with the illumination of our environment from our Sun.
Sun is a natural source of energy and it provides light on earth. Light is a form of energy and it is very important for us in various ways therefore, the importance of sun as a natural source of energy is increased. Light energy, which sun provides to us is converted into chemical energy and plants use this energy to form food for us. The resources present on earth are not all renewable but sun provides us energy which is abundant and infinite, that is why sun is considered as a major natural source of energy.
We are getting vitamin D from the sun rays and also for phototsynthesis sun light is very important.because starch is produced by plants in the presence of sun light only
The sun is important because we need the sun to survive.we need it to live off land like animals,vegetables,plants,I'm sure some more things.If we didnt have the sun everything would not exsist. DESTINY SARMIENTO

The Sun is the star at the center of the Solar System. It has a diameter of about 1,392,000 kilometers (865,000 mi) (about 109 Earths), and its mass (about 2 × 1030 kilograms, 330,000 times that of Earth) accounts for about 99.86% of the total mass of the Solar System; the remainder consists of the planets (including Earth), dwarf planets, satellites, small Solar System bodies and dust in orbit.[10] About three-quarters of the Sun's mass consists of hydrogen, while most of the rest is helium. Less than 2% consists of other elements, including iron, oxygen, carbon, neon, and others.[11]
The Sun's color is white, although from the surface of the Earth it may appear yellow because of atmospheric scattering.[12] Its stellar classification, based on spectral class, is G2V, and is informally designated a yellow star, because the majority of its radiation is in the yellow-green portion of the visible spectrum.[13] In this spectral class label, G2 indicates its surface temperature of approximately 5,778 K (5,505 °C; 9,941 °F), and V (Roman five) indicates that the Sun, like most stars, is a main sequence star, and thus generates its energy by nuclear fusion of hydrogen nuclei into helium. In its core, the sun fuses 430–600 million tons of hydrogen each second. Once regarded by astronomers as a small and relatively insignificant star, the Sun is now presumed to be brighter than about 85% of the stars in the Milky Way galaxy, most of which are red dwarfs.[14][15] The absolute magnitude of the Sun is +4.83; however, as the star closest to Earth, the Sun is the brightest object in the sky with an apparent magnitude of −26.74.[16][17] The Sun's hot corona continuously expands in space creating the solar wind, a hypersonic stream of charged particles that extends to the heliopause at roughly 100 astronomical units. The bubble in the interstellar medium formed by the solar wind, the heliosphere, is the largest continuous structure in the Solar System.[18][19]
The Sun is currently traveling through the Local Interstellar Cloud in the Local Bubble zone, within the inner rim of the Orion Arm of the Milky Way galaxy. Of the 50 nearest stellar systems within 17 light-years from Earth, the Sun ranks 4th in mass.[20] The Sun orbits the center of the Milky Way at a distance of approximately 24,000–26,000 light years from the galactic center, completing one clockwise orbit, as viewed from the galactic north pole, in about 225–250 million years.
The mean distance of the Sun from the Earth is approximately 149.6 million kilometers (1 AU), though this varies as the Earth moves from perihelion in January to aphelion in July.[21] At this average distance, light travels from the Sun to Earth in about 8 minutes and 19 seconds. The energy of this sunlight supports almost all life on Earth by photosynthesis,[22] and drives Earth's climate and weather. The enormous effect of the Sun on the Earth has been recognized since prehistoric times, and the Sun has been regarded by some cultures as a deity. An accurate scientific understanding of the Sun developed slowly, and as recently as the 19th century prominent scientists had little knowledge of the Sun's physical composition and source of energy. This understanding is still developing; there are a number of present-day anomalies in the Sun's behavior that remain unexplained.
With out access to the sun it can lead to things like depression it can effect our economy and it can cause deseases like rickets and one called seasonal affective disorder also known as SAD. Not only that but it can improve friendships and help with crops in other poorer countries, besides the midday sun could be good for you as it can increase the rate of vitamin d produce in our skin but too much can cause skin cancers and will age you increadably.
It provides sunlight which helps us see and it helps the plants to grow and it is important because it helps us see and if we didn't have sunlight we would die.
