Let's say you ride a bike on a warm summer day. The sky was also bright outside.

Now, 92.96 million miles away, the sun is extinguished. It suddenly disappeared. First of all, we will not immediately notice. It takes 8.27 minutes for the Earth to become dark. So, we have 8 minutes of sunshine left.
It gets dark after 6 minutes: You park your bike outside your favorite deli. After you've eaten fast food, you go outside and go biking.
It turned dark after 3 minutes: Today is still a clear day. You jump on your bike and ride home.
It turns dark after 3 seconds: you ride your bike home. Suddenly, you notice that everything starts to fade. Everything in front of me slowly faded into darkness. Soon, you hear several cars stop and several more collide. It's no different than you. You hit your bike into a light pole that hasn't been turned on yet. You fell and scratched your elbow. No big deal.
The whole earth is dark. There was no longer natural sunlight, and the stars of the Milky Way began to appear in the sky.
The sun is gone. People panicked and started robbing the store, and everyone went crazy. The weather was a bit cold but still surprisingly sunny. You don't need a jacket to keep you out in the cold.

1 day without sun: the temperature got a little cooler, but perfectly livable. Almost all the plants are still alive. People still panic and think it's the end of the world.
1 week without sun: things get unusual. First, you might experience a new ice age. The global temperature is 32 degrees Celsius. No food shortages, no oxygen shortages, etc. Power is still valid (assuming everyone is still doing most of the work).
2 weeks without sun: Nothing has really changed. Of course, the weather is still a little cooler. A lot of the little plants are dead. However, we still have enough oxygen to survive in the atmosphere for a while. There is no food shortage at the moment, but as you can imagine, many people are still attacking stores around the world.

Let's speed up the process a little bit.
1 year without the sun: Now, we are talking about serious changes. Global temperatures are around -150 degrees Fahrenheit. We can still use electricity. You can only sit in your house for warmth, because the weather will get colder. We still have enough oxygen. There are also some plants that are still alive due to slow metabolism, such as large trees. The surface of the ocean slowly freezes, making the earth an ice ball.
There has been no sun for decades: this is where we panic. Remember, we still have enough oxygen. The big tree is still alive. But the weather has become extremely cold, and some people have died. If we don't come up with some plan, there will be a food shortage. The only warm place on Earth is either a well-heated home or the bottom of the ocean floor near a hot vent.
1000 years without the sun: you can only pray. We still have a little oxygen. The global temperature is -400 degrees Fahrenheit. At this point, the Earth is just an ice hockey ball. At this point, the Earth's atmosphere will disappear. So just say goodbye to oxygen and then welcome all the radiation that will enter our once beautiful Earth. Is there anything that can survive on Earth? yes.

Near the hot vents on the seabed, there are also organisms inside. They will survive for billions of years. They don't need sunlight. You know, the surface of the ocean is frozen.

Few Things to Note:
Some things to note:
This will never happen. The sun is physically unlikely to disappear or burn. So enjoy vitamin D to the fullest. :)
And, even if the sun disappears. We will no longer revolve around the sun. We will fly into outer space. We either continue to fly in space, into a black hole, or be caught by another star that will allow us to survive. That would be cool, right?
Imagine, in a new solar system, the Earth revolves around South Gate TWO or whatever. New planets, new discoveries.
Anyway, hope this helps!
