This answer depends on the size of the black hole. Black holes devour anything that falls onto the event horizon. As a black hole eats any and everything around it, it will grow. These black holes will exist as long as the universe exists. Small black holes do evaporate and disappear. This is because of something known as Hawking Radiation. Hawking Radiation is present in all Black Holes but its effects are inversely proportional to the mass of the black hole. This means that the larger the mass of the black hole the less the effect of the radiation is. A Black hole the mass of the Moon would evaporate almost instantly and the smaller the mass, the faster it will evaporate. You may think that a black hole that is larger but has nothing to consume will eventually evaporate, but you'd be wrong. Black Holes not only absorb stars and other objects, but it also feeds on the heat in space. Space is 2.7 kelvin, this is known as the Cosmic Microwave Background. A Black hole with a Solar mass of the sun will have a Hawking Temperature of about 100 Nanokelvins. This is far less then the 2.7 kelvins that space is. This is why large black holes will live as long as the universe itself, and small black holes such as those that could possibly be made with the Large Hadron Collider will never just stay open and consume the Earth. It is physically impossible due to the Hawking Radiation.
Answer #2. #1 is correct however I would like to correct the everlasting black holes bit. No black holes will last as long as the universe. Supermassives have the advantage of accreting from the CMB right now. As the CMB cools they'll get less and less energy. Eventualy it's gonna hit an equilibrium where they're radiating as much mass as they're gaining through the CMB, then the scales will tip and all black holes will start slowly evaporating like their stellar-sized cousins did, ableit vastly slower, unless they continue accreting matter. Problem is, when that happens, the universe will be essentially dead, there will be no more stars to eat. Just vast nothingness full of supermassive black holes slowly dying and drifting masses of carbon (Black dwarf stellar remnants). So basically, no black holes live forever.
No
Black holes will help us know more about how things grow, live and die. Rod's answer ; Black holes help us to know that if we don't ask Jesus into our hearts before we die, we will be in one forever. Just finishing my book showing the similarities between black holes and Hell and the Lake of Fire. No joke. God's out there for real!
Black holes do not die but they can evaporate.
Black holes are round because they are formed from dead stars and white holes. As you can guess a star is a sphere and that is why black holes are round.
Yes. They get sucked into black holes all the time!
No
Science at this time can find no end to black holes. They seem to last forever.

depending on the size, stellar black hole , yes. Supermassive black holes, no, once you reach the singulaity you are outside of the universe, and you vanish, forever, you don't exist anymore.
stellar black holes were stars (these are large)primordial black holes were pieces of the big bang (these are microscopic)
No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.No. It certainly has black holes, but it has other things as well.

No, they do not live in holes.

There are no black holes in our solar system
They are called "black holes".
