The Sun is the main source of energy for most living things on earth.
If you look at a food web, the Sun first has to give sunlight to the producers, or plants. These plants use the sunlight to photosynthesize and make glucose to survive. Herbivores, or plant eaters, eat these plants for their glucose and other nutrients to survive. These herbivores are primary consumers. There are carnivores, meat eaters, that eat these herbivores, and these are the secondary consumers. Then, more carnivores eat the carnivores that eat the herbivores, and these are the tertiary consumers.
Basically, the energy of the sun flows from plants, to herbivores, to carnivores, and to top-level carnivores. 10% of the energy made by the plants goes to the herbivores, and 10% of that to the carnivores, and then another 10% to the top-level carnivores. The energy of the Sun is transferred throughout the entire food web, and without food, nothing on earth can survive.
Thus, the point of the Sun is to help the living organisms on earth survive.

∙ 13y agoThe Sun holds everything together. It helps gravity stay in tact and gives any planet close enough heat. It is actually a medium sized star. Sun its just its name. There are stars out there that are WAY bigger, we just can't tell by looking at them because they are so far away.

Is the subsolar point on a planet the point that is closest to the sun?
No. The "sub-solar" point is that point on the Earth where the Sun is STRAIGHT UP from there.

Is the equator the closest point to the sun?
no
What planet's orbit is not centered on the sun?
That applies to all planets. Planets go around the Sun in elipses - the Sun is at one of the focal point of the elipse. The focal point is not the center.
When the Earth is in its orbit and is at its closest point to the sun it is said to be at?
The earth's orbit around the sun is not a perfect circle, so there is a point at which we are nearest to the sun, and a point at which we are farthest from it. The point in the orbit at which we are nearest the sun is called "perihelion". The earth passes that point at some time during the first few days in January. In 2011, it happened on January 3. The point in the orbit at which we are farthest from the sun is called "aphelion". We pass it at some time during the first few days of July.

When is the speed of a planet revolving around the sun the slowest?
When it is farthest from the Sun. This point is known as aphelion. *Aphelion = Furthest point from the Sun.
What point in a planets oribits is closest to the sun?
perihelion is the point in a planets orbit when it is closest to the sun
What are sun angles?

What is the farthest point of a planet's orbit from the sun?
The 'Apogee'. is the furthest point on a planets orbital track about the Sun. The 'Perigee' is the corresponding nearest point.
Where is the current sub-solar point?
The sub-solar point is the point on the Earth where the sun the sun is directly overhead. Currently, the sub-solar point is Tamaulipas, Mexico.
What is the term for when a planet is at the point of its orbit nearest the sun?
The closest point to the Sun in a planet's orbit is called perihelion. The furthest point is called aphelion. Phil
What is the point of the planet Mercury closest to the sun?
Mercury rotates (slowly) as it orbits the Sun. So, the point that's closest to the Sun changes with time.
What do you call to the point where the earth is fastest from the sun?
Aphelion is the point in the orbit of a planet, asteroid, or comet at which it is furthest from the sun.
What is the point when earth is closest to the sun calles?
That's the point in Earth's orbit called "perihelion".The point in the orbit that's farthest from the sun is "aphelion".
